Core Idea¶

Semantic Narrowing and Widening are two directional sub-types of semantic shift^[1], distinguishable as:

(1) narrowing (specialization) — the lexical item undergoes a scope reduction: its reference set shrinks over time; the word applies to fewer entities than before. Classic examples: meat (once meant any solid food, now specifically animal flesh); deer (once meant any wild quadruped, now specifically the cervid family). This narrowing typically emerges through domain specialization, where experts and practitioners need tighter, more precise lexical categories.

(2) widening (generalization, broadening) — the original semantic range expands; the directional shift marks the term's application to increasingly broader sets. The word applies to more entities than before: dog (originally a specific breed, now the whole Canis familiaris); Kleenex, Xerox, Google widening from brand-proprietary to generic category-level usage. Widening arises typically through generic extension, where mass uptake and abstraction diffuse specialist terms into generalist domains.

(3) narrowing and widening are the specialization-vs-generalization axis: these are the two most empirically frequent trajectories of semantic change. The social-pragmatic cause differs markedly between them: narrowing tends to arise through technical codification (legal statutes, medical taxonomy, engineering specification); widening tends to arise through popularization and metaphorical extension (brand genericide, advertising saturation, everyday discourse pressure).

(4) narrowing and widening are analytically dual: the conventionalization endpoint depends on which reference-frame is primary. The same shift can appear as narrowing from one community's perspective ("in my subfield, model means statistical model") and widening from another broader perspective ("across the company, model now includes process diagrams, organizational structures, and financial projections"). No absolute directionality exists without an anchor community.

How would you explain it like I'm…

Words shrinking and stretching

Words can change what they mean over time. Sometimes a word starts out meaning lots of things and ends up meaning just one — like 'meat,' which used to mean any food. Other times a word starts out meaning one thing and grows to mean lots — like 'Kleenex,' a brand name that now means any tissue. One shrinks, one stretches.

Meanings getting narrower or wider

Words don't keep the same meaning forever. Narrowing is when a word's meaning shrinks: 'meat' used to mean any food, but now means just animal flesh. 'Deer' used to mean any wild animal, now just the deer family. Widening is the opposite — a word's meaning stretches: 'dog' was once a specific breed but now covers all dogs, and brand names like 'Google' and 'Kleenex' grew to mean any search or tissue. Narrowing often happens when experts need precise words; widening often happens when popular use spreads a word everywhere.

Semantic narrowing and widening

Semantic narrowing and widening are two opposite ways a word's meaning can shift over time. In narrowing (specialization), a word's reference set shrinks: 'meat' once meant any solid food but now means animal flesh; 'deer' once meant any wild quadruped but now refers only to cervids. In widening (generalization), the reference set expands: 'dog' once named a specific breed and now covers all of Canis familiaris; brand names like Kleenex, Xerox, and Google have widened into generic categories. Narrowing typically arises through technical codification — law, medicine, engineering — where experts need precise categories. Widening typically arises through popularization and metaphorical extension. The two directions are also analytically dual: the same shift can look like narrowing from one community's view and widening from a broader one, so the direction depends on which community is the reference frame.

Semantic narrowing and widening are two directional sub-types of semantic shift, first systematized by Bréal (1897). Narrowing (specialization) is the case where a lexical item undergoes scope reduction: its reference set shrinks over time and the word applies to fewer entities than before. Canonical examples: 'meat' (once any solid food, now specifically animal flesh) and 'deer' (once any wild quadruped, now the cervid family). Narrowing typically emerges through domain specialization — experts and practitioners need tighter, more precise lexical categories codified through law, medicine, or engineering. Widening (generalization or broadening) is the inverse: the original semantic range expands, and the word applies to a larger reference set. Examples include 'dog' (originally a specific breed, now the whole species Canis familiaris) and brand names — Kleenex, Xerox, Google — generalizing from brand-proprietary terms to category-level usage (a phenomenon called genericide). Widening typically arises through popularization and metaphorical extension, driven by mass uptake and discourse pressure. Together these are the specialization-vs-generalization axis, empirically the two most frequent trajectories of lexical change. They are also analytically dual: the same shift can appear as narrowing from one community's perspective ('in my subfield, model means statistical model') and widening from a broader perspective. There is no absolute directionality without an anchor community.

Structural Signature¶

The lexical item undergoes a directed change in the cardinality of its reference set, observed synchronically as a difference between older and newer usage or across speech communities. The mechanism is selective application: some contexts propagate the newer scope, others retain the older. Narrowing is often driven by precision pressure — experts need a tighter label to avoid ambiguity in technical discourse^[2]. Widening is often driven by salience and frequency — the prototypical instance becomes the category label through repetition and mass uptake. The social-pragmatic cause shapes both: narrowing through institutional standardization (legal codes, medical registries, engineering manuals); widening through popular adoption and colloquial expansion.

The dual character — the specialization-vs-generalization axis — makes the distinction dependent on which speech community is treated as reference. The conventionalization endpoint is the point where the new scope becomes entrenched in dictionaries, glossaries, and institutional memory, effectively replacing or supplementing the earlier scope.

What It Is Not¶

Not semantic shift in general — semantic shift is the umbrella process of meaning change of any kind. Narrowing and widening are two of its type-specializations^[1]; pejoration, amelioration, metonymic extension, and taboo replacement are others. The two primes are always co-taught but specialize the shift concept by directionality. Narrowing and widening specifically track extensional (reference-set size) change rather than connotational (evaluative) change.
Not polysemy — polysemy is the synchronic state of a term having multiple related senses. Narrowing and widening are the diachronic processes by which that state is often reached (or departed from). A term can be polysemous without having recently narrowed or widened; polysemy can also resolve by one sense dropping out, itself a form of narrowing.
Not metaphor alone — metaphor is one social-pragmatic cause among many (metonymy, ellipsis, analogical extension, register-shifting). Narrowing and widening encompass metaphorical mechanisms but also grammaticalization, domain-specific jargon formation, and institutional standardization.
Not borrowing or code-switching — borrowing introduces new forms; code-switching is a speaker's move between established codes. Narrowing and widening describe change within a single code's lexicon over time or across sub-communities within that code.
Not neologism — neologism creates a new form for a new meaning. Narrowing and widening operate on existing forms whose scope changes while form remains stable.
Not register-shifting alone — register (formal/informal, technical/colloquial) can activate different senses of a term, but that synchronic variation is distinct from diachronic scope narrowing or widening.
Not arbitrary or unmotivated change — both narrowing and widening follow patterned trajectories driven by social, cognitive, and pragmatic pressures. Directionality is recoverable and predictable given institutional or community context.

Broad Use¶

Historical linguistics (core domain) — Bréal's foundational 1897 Essai de Sémantique^[1] established narrowing and widening as canonical semantic-change types. Traugott and Dasher's^[3] Regularity in Semantic Change (2002) systematized widening through grammaticalization and subjectification. Blank and Koch's Historical Semantics and Cognition (1999) mapped narrowing and widening onto prototype-theory explanations.
Terminology management and standardization — Standards bodies and technical writers deliberately narrow terms (ISO specifications, medical nomenclature, legal codes). Narrowing increases precision for contracts, protocols, and specialist communication but raises barriers for generalists. Must counteract ambient widening in high-stakes contexts (patent law, safety specifications).
Brand management and trademark law — Brand genericide is a canonical widening risk: Escalator, Aspirin, Thermos, Kleenex widened until they lost trademark protection. Brand managers invest in defensive narrowing (restricting "Xerox" to the company's equipment, not the verb "to xerox"). Trademark dilution law recognizes widening as a threat to brand equity.
Scientific nomenclature and medical terminology — Biological, chemical, and medical vocabularies are engineered to be narrow and unambiguous in clinical contexts. Popular usage and mass-media discussion systematically widen these terms (e.g., schizophrenia contrasted in clinical vs. colloquial use; trauma narrowed in psychology, widened in popular discourse). Language acquisition research^[4] (Clark 1973) shows children's overextension as a widening error and underextension as narrowing.
Software-engineering terminology and computational linguistics — "Service" narrowed inside service-oriented architecture communities, then widened as microservices popularized the term. "Agent" narrowed in classical AI contexts, widened in generic usage, narrowed again in modern LLM-agent terminology. These cycles reflect shifts in professional and public discourse priorities.
Legal drafting and statutory interpretation — Statutory definitions deliberately narrow common words to precise categorical boundaries ("motor vehicle operator" narrowed from the general "driver"). Precedent and analogical reasoning sometimes widen those narrow definitions over time. Constitutional terms drift (e.g., "unreasonable search" narrowed and widened repeatedly over decades of jurisprudence).
Corporate glossaries and organizational onboarding — New hires encounter terms whose corporate-internal meaning has narrowed or widened from the general sense. Marketing "solutions" narrows to specific product bundles internally. Support "tickets" widen to include informal discussions. Glossaries document the corporate-specific scope to prevent cross-team miscommunication.
Translation studies and cross-linguistic false cognates — Cognate terms across languages often diverge through differential narrowing and widening. Spanish realidad and English reality have partially narrowed differently; French sensible has narrowed to "sensitive" while English sensible means "reasonable." These divergences create systematic false-friend errors.
Language acquisition and developmental semantics — Children's overextensions (calling all four-legged animals "dog") are narrowing errors in acquisition. Underextensions (using "dog" only for the pet collie, not the neighbor's poodle) are widening errors. Error patterns predict typical developmental trajectories.
Marketing and brand genericization strategy — Proprietary brand widening to generic verb or noun is both legal risk and market signal. "To google," "to xerox," "to kleenex" as widened verbs mark successful penetration but also signal loss of trademark exclusivity. Brand strategy oscillates between deliberate narrowing (premium positioning) and widening (market dominance).

Clarity¶

Distinguishes the directional shift of semantic change rather than leaving change as an undifferentiated process. Analysts can ask of any shift in a term's usage: is this term becoming more specialized or more generic? The answer carries practical implications[^bybee-2015]:

Narrowing drives terminological crowding: new words are needed for the generalities the old term no longer covers. When "mouse" narrowed from the rodent category to "computer input device," the old referent required circumlocution ("field mouse," "gray mouse").
Widening drives genericide risk and cross-subculture miscommunication: listeners interpret the term by their home scope. When "algorithm" widened from computer science into everyday discourse, novice speakers misapply the term to non-computational problem-solving.

Without the narrowing–widening distinction, "semantic shift" is the only available label, and the direction-specific dynamics remain invisible to practitioners.

Manages Complexity¶

Lets practitioners predict typical patterns[^croft-2000]: domain specialists will narrow inherited general terms (making domain-internal communication efficient at the cost of boundary miscommunication); mass-market uptake will widen specialist terms (making general communication accessible at the cost of specialist precision). Knowing these directional vectors, organizations can design vocabulary-stewardship interventions appropriate to the direction of drift:

For widening terms: replacement coinage (introduce a narrower term for the abandoned specialist sense), glossary updates, and boundary-marking documentation ("in this context, feature means...").
For narrowing terms: cross-reference strategies (linking the narrow specialist sense back to the general category) and explicit scope-declaration in technical writing.

A widening term often needs new replacement coinage; a narrowing term often needs explicit cross-reference to the original general sense. Organizations that miss this distinction waste resources policing narrowed terms that have already drifted or attempting to narrow terms that are already on a widening trajectory^[5].

Abstract Reasoning¶

Generalizes to any hierarchical category system where labels attach at one level but can drift up or down the hierarchy. Software type systems experience narrowing (a generic interface becoming domain-specific through subclass proliferation) and widening (a specific class generalizing as its interface is reused). Legal categories experience both (case-specific rulings narrowing precedent categories; analogical reasoning widening them). Organizational role titles drift similarly (the Chief Technology Officer role once meant individual contributor–architect; the role widened to cover executive responsibilities; in some firms it has re-narrowed to pure strategy). Cognitive categories in child development show the same patterns: "dog" widens from the pet collie to all similar-shaped animals, then re-narrows as taxonomic distinctions are learned.

The prime teaches the analyst to ask of any category-label system: which labels are specializing, which generalizing, and what does that imply for users of the system? The answer predicts confusion patterns, training needs, and intervention opportunities.

Knowledge Transfer¶

Direction	Mechanism	Example	Typical Driver	Reference
Narrowing	Domain specialization	"Meat" from any food → animal flesh	Expert community precision	Bréal 1897; Ullmann 1957
Narrowing	Legal codification	"Driver" → licensed motor-vehicle operator	Statute drafting	—
Narrowing	Technical standardization	"Service" inside SOA	Architecture community	—
Narrowing	Tabooed-sense retreat	"Gay" to sexual orientation (and loss of merry)	Social use pressure	—
Widening	Brand → category	Kleenex, Google, Xerox	Mass adoption of brand	—
Widening	Metaphorical extension	"Platform" from physical stage to digital infrastructure	Industry generalization	Lakoff-Johnson metaphor theory
Widening	Specialist → generalist	"Algorithm" from CS to everyday discourse	Popularization of technical term	—
Widening	Generic → intensified	"Awesome" from fear-inspiring to high approval	Mass-media uptake	—

Across rows, the directional shift is identifiable and the social-pragmatic cause predicts similar shifts in analogous situations. Practitioners in any vocabulary-heavy domain (law, medicine, technology, corporate operations) can audit their term base by asking which terms have narrowed, which have widened, and which need stewardship against further drift.

Examples¶

Formal / Abstract¶

"Girl" as narrowing across Anglo-Saxon history[^millward-1996]: Old English gyrl meant "young person of either sex" — a wide category with no gender restriction. By Middle English, the term had narrowed significantly to predominantly feminine reference, though "girl" retained some gender-neutral force (e.g., "a fellow girl" meaning a young person of any gender in certain dialects). By Early Modern English, the narrowing was complete: girl = "young female." The Oxford English Dictionary documents this as a classic example of narrowing driven by pragmatic pressure (women's social roles narrowed the referential scope). This is Bréal's and Ullmann's canonical example of narrowing: the old broader sense is lost; the new narrow sense becomes the unmarked default.

Traugott-Dasher unidirectionality hypothesis[^traugott-dasher-2002]: Traugott and Dasher argue that widening through grammaticalization is the dominant pattern in English semantic change. Widening occurs as terms undergo "subjectification" — shifting from objective description ("That's a long way") to subjective evaluation ("That's quite a journey" = "considerable effort"). The hypothesis predicts that narrowing is less common and often reversible, while widening through grammaticalization is unidirectional. This remains debated in the field but structures much diachronic semantic research.

Prototype-theory explanation[^blank-1999]: Blank and Koch map narrowing and widening onto cognitive-prototype theory. Narrowing occurs when a prototype instance becomes the only category label (the most typical "bird" was a sparrow or robin in medieval English; "bird" nearly narrowed to that prototype). Widening occurs when a category label extends from prototype to periphery (a robin is prototypically a "bird," but so are ostriches, penguins, and hummingbirds — the category widened by including periphery). This cognitive account explains both the directionality and the motivations for change.

Applied / Industry¶

Xerox and Google: Brand to Verb Widening^[5] — Xerox Corporation's trademark name for photocopying machines widened into a generic verb: "to xerox" = "to photocopy" (regardless of brand). Google's brand name widened similarly: "to google" = "to search the internet" (not just on Google). Both widening events were initially defended as trademark-dilution risks; both became market-dominance signals. The legal-economic concern: widening erodes exclusivity (anyone can google with Bing; anyone can xerox with a Canon). Brand strategy must oscillate between accepting widening (market reach) and defending narrowing (trademark exclusivity). The narrowing effort: companies now say "use Google's search engine to search" rather than "google it," attempting to re-narrow the term to the company-specific service. This oscillation between widening (natural market process) and narrowing (legal-defensive strategy) is constant in trademark management.

Software "Feature" Widening: Corporate Glossary Case Study^[6] — A mid-sized software company's glossary documented feature originally as "user-facing capability shipped in a release" (narrow engineering usage). Over five years, as marketing, sales, and support teams adopted the term, feature widened to mean "any distinguishable product capability at any level" — from a button label to a major subsystem to a pricing tier. By year five, standup reports and roadmap slides used feature with incompatible scopes, producing recurring miscommunication: an engineer reporting "3 features shipped this sprint" was granular; a sales rep saying "your product has 47 features" was coarse; a support engineer triaging "feature not working" operated at a third grain. The terminology-stewardship team diagnosed widening from a narrow-specialist origin and introduced shippable-unit for the narrow engineering meaning, retained feature as the broad product-catalogue term, and published the distinction. Two quarters later, cross-team reports improved — widening was accepted, the narrow sense had a new home. Direct operational use of the narrowing–widening framework solved a real communication problem.

Medical "Trauma": Narrowing in Clinical, Widening in Popular Discourse^[7] — In clinical psychology and psychiatry, trauma narrowed to specific diagnostic categories (PTSD-qualifying events, DSM criteria). In popular discourse (social media, journalism, everyday conversation), trauma widened to include any distressing experience ("I'm still traumatized from that awkward meeting," "financial trauma"). Medical professionals encounter constant widening pressure in popular usage; they resist narrowing by publishing precise definitions and insisting on clinically bounded usage. The gap between narrow clinical and wide popular scope creates miscommunication: a therapist's "trauma" and a patient's "trauma" may refer to incompatible referent sets. Terminology stewardship requires explicit scope-declaration in clinical intake forms and patient education.

Structural Tensions¶

T1 — Precision vs. accessibility; narrowing cost and widening benefit. Narrowing a term increases precision for specialists (a narrowed term unambiguously identifies a category in technical discourse) but raises a barrier for generalists who must learn the restricted sense. Widening lowers the barrier to entry (the same term is recognized across communities) but costs precision (miscommunication at boundaries). No steady-state resolves the trade-off; communities continuously negotiate it through glossaries, training, and context-marking.

T2 — Directional symmetry vs. empirical asymmetry; Traugott unidirectionality hypothesis. In principle narrowing and widening are symmetrical processes of scope change. Empirically, widening appears more common in recent English (grammaticalization, brand genericide, metaphorical extension, social-media diffusion) while narrowing predominates in technical-term formation and legal codification. The asymmetry reflects the asymmetric pressures of mass culture (democratizing, widening) vs. expert practice (standardizing, narrowing). This tension structures debates in historical semantics about whether language change is more often "up" the hierarchy (widening) or "down" (narrowing).

T3 — Acquisition errors: overextension (widening) vs. underextension (narrowing). Children learning vocabulary systematically make both errors: overextending "dog" to all four-legged animals (widening) and underextending "dog" to only the family pet (narrowing). These are not errors in the child's logic but rather mismatches between the child's scope and the community's scope. The tension: are these the same mechanisms as historical semantic change, or are acquisition errors distinct processes? Clark (1973) argues they reflect the same directionality pressures, a hypothesis still debated.

T4 — Trademark genericization as legal and market risk. Brand widening is both a sign of market dominance ("everyone Googles") and a legal threat (widening can cost trademark protection). Companies continuously defend against widening while accepting the market benefits of brand penetration. This tension is irresolvable: defending narrowing costs market reach; accepting widening costs legal exclusivity. Brand management cycles between strategies.

T5 — Specialized-domain narrowing vs. generalist-interface widening. Technical fields narrow inherited general terms for precision (medical "virus," legal "consideration," computing "cache"), but as those fields grow and interface with the public, the terms widen back to loose colloquial sense. Scientists resist widening; the public resists learning narrow specialist senses. This tension is particularly acute in health communication, legal literacy, and technology onboarding.

T6 — Cross-cultural and cross-linguistic variation in narrowing/widening trajectories. The same concept narrows differently across languages and cultures. English "bird" has different prototype-based scope than German Vogel or Japanese tori. "Privacy" narrowed differently in English-speaking vs. European contexts. "Family" widens differently in North American vs. East Asian contexts. This tension reflects deep differences in institutional and cognitive categorization. Translation and cross-cultural communication require explicit scope-negotiation; assuming narrowing/widening patterns transfer across languages creates systematic false-friend errors.

Structural–Framed Character¶

Semantic Narrowing and Widening is a hybrid on the structural–framed spectrum, with the frame carrying real weight. Part of it is a bare pattern—a directed change in the size of a category's reference set, either shrinking or expanding over time. But part of it is a frame inherited from linguistics, where the thing changing is specifically a word's conventional meaning within a speech community.

The structural element is abstract enough to state without language: a labeled set whose membership contracts (specialization) or grows (generalization) along a temporal trajectory, a pattern visible wherever a category's scope drifts—a brand name that comes to denote a whole product class, a technical term that gradually covers more cases. That much is a directional change in cardinality. But the prime's home vocabulary is lexical and social: it concerns the reference of a stable signifier across speech communities, the mechanism of selective application driven by domain specialization, and historical examples like meat once meaning any food and now only flesh. That framing imports assumptions about convention, usage, and how communities of speakers settle meaning that a bare set-resizing pattern does not need. With a genuine structural core but a substantial linguistic frame, it sits mid-spectrum, leaning framed.

Substrate Independence¶

Semantic Narrowing and Widening is among the most substrate-tethered entries — composite 1 / 5 on the substrate-independence scale. The pattern documents how the scope of a word's meaning contracts or expands over time, and its structural signature — a change in the cardinality of a reference set, selectively applied and propagated through context — is inherently linguistic. Carrying it elsewhere, as in 'narrowing organizational focus,' is metaphor rather than structural transfer. It is a useful pattern within language change, but it does not lift cleanly off its linguistic home medium to function as a substrate-independent prime.

Relationships to Other Primes¶

Parents (1) — more general patterns this builds on

Semantic Narrowing and Widening is a kind of Semantic Shift

Semantic narrowing and widening is a specialization of semantic shift: it names two directional sub-types of meaning-change identified within Bréal's broader typology. It inherits semantic shift's four-part structure — the lexical item, the diachronic trajectory, the typology of mechanisms, the social-pragmatic-cognitive forces — and particularizes it to the scope-change axis. Narrowing is the specialization-direction sub-type; widening is the generalization-direction sub-type; both are species of the broader shift category.

Not to Be Confused With¶

Semantic Narrowing and Widening must be distinguished from Semantic Shift, their parent concept (similarity 0.767 with semantic_shift, the nearest neighbor). Semantic Shift is the umbrella term encompassing all types of meaning change over time: narrowing, widening, amelioration (positive connotation increase), pejoration (negative connotation increase), metonymic extension, metaphorical shifts, bleaching, and taboo replacement. Narrowing and widening are two of the major directional subtypes within this broader category. The distinction matters because narrowing and widening track extensional change (the size of the reference set), while other semantic shifts track connotational change (evaluative tone) or relational change (the mapping between signifier and signified shifts through metaphor or metonymy). A term can undergo pejoration (acquiring negative connotation) without narrowing or widening: villain has pejorated (now strongly negative) without necessarily shrinking or expanding the set of people called villains. Conversely, dog widening to include poodles, terriers, and dachshunds involves no pejoration or amelioration—the connotation remains stable while the extensional scope shifts. The narrowing–widening framework highlights directionality of scope change; the broader semantic-shift framework encompasses this and other dimensions simultaneously. When a practitioner asks "is this term getting more or less specific?" they are asking about narrowing or widening; when they ask "is this term becoming more positive or more negative?" they are asking about amelioration or pejoration, which are distinct dimensions of semantic change.

Nor is Semantic Narrowing and Widening identical to Signifier–Signified Duality, though both involve the relationship between words and their meanings. The signifier–signified duality is a structural linguistics concept describing the fundamental two-part relationship between a word's form (the signifier, the sound or written symbol) and the concept it denotes (the signified, the mental meaning). Narrowing and widening, by contrast, describe the historical change in that signified: the same signifier (the word form, stable) is applied to a different-sized set of entities over time. When dog widened from a specific breed to the whole species, the signifier "dog" remained stable, but the signified (what the term refers to) expanded. The duality is the structural pairing itself—how forms and meanings bind together; narrowing and widening describe how that pairing evolves. A practitioner interested in the duality asks "what is the nature of the relationship between form and meaning?" A practitioner interested in narrowing–widening asks "how has the meaning of this form changed over time?" Both questions are about semiotics, but they address different aspects.

Finally, Semantic Narrowing and Widening differs from Register (or Style) Shifting, though both involve variation in how terms are used. Register shifting is synchronic (happening in the present)—a speaker adjusts the formality, technicality, or audience-appropriateness of their language based on context. Using "gonna" with friends but "going to" in formal settings; using medical jargon in the hospital but lay language at the dinner table. Register shifting does not change the word's meaning or scope; it changes which meaning or sense a speaker activates in a given context. Narrowing and widening, by contrast, are diachronic (happening over time)—a term's reference set actually shrinks or expands as communities collectively use it differently over months, years, or generations. When trauma widened from a narrow clinical diagnostic category to popular use, that is not register shifting (the same speaker doesn't alternate between narrow and wide usage depending on setting); it is a genuine historical shift where the term's scope changed across the speech community. A term can experience both: feather narrowed historically (from any lightweight plume to bird feathers specifically), and speakers also use register-appropriate variation (technical "feather" in engineering vs. colloquial "feather" in everyday speech). But the narrow–wide distinction tracks permanent historical change, while register tracks context-dependent situational variation.

Semantic Narrowing and Widening also differs from Polysemy (having multiple related meanings), though the two are deeply connected. Polysemy describes a synchronic state: a single word currently has multiple senses that speakers recognize as related. Bank is polysemous—it means both a financial institution and the edge of a river, and speakers recognize the senses as linked (sitting on a riverbank; sitting in the bank metaphorically). Narrowing and widening describe the diachronic process by which polysemy often arises or resolves. Bank became polysemous through a historical metaphorical extension (the river edge, the metaphorically "edged" financial institution); that extension is a widening process. Over time, if one sense of a polysemous word drops out of use, it is a narrowing. Polysemy is the state; narrowing and widening are the processes that create, maintain, or resolve that state.
