Historical & Quantitative Linguistics

← Back to Domain-Specific Families

Abstractions about language change, borrowing, lexicalization, comparative reconstruction, corpus evidence, language relatedness, and quantitative stylistic analysis.

14 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Analogical change — Language change in which a form or meaning is remodeled after a perceived pattern elsewhere in the linguistic system.
• Anatolian hypothesis — The archaeolinguistic hypothesis that Proto-Indo-European languages dispersed from Neolithic Anatolia with early farming from roughly the seventh millennium BCE, competing with later Pontic-Caspian steppe models.
• Combinatorial method (linguistics) — A contextual method for inferring an undeciphered language’s word classes, meanings, and grammar without a known relative or large bilingual corpus.
• Corpus linguistics — An empirical approach to language that analyzes systematically assembled collections of authentic spoken, written or multimodal usage.
• Historical glottometry — A quantitative non-tree method for historical language subgrouping that measures overlapping innovations to reconstruct entangled genealogies in dialect continua and linkages.
• Lexicalization — The process by which a meaning, phrase or word-formation pattern becomes established as a conventional lexical item or stored unit of a language.
• Lexicostatistics — A comparative-linguistic method that quantifies shared basic-vocabulary cognates among languages to estimate degrees of lexical relationship.
• Quantitative comparative linguistics — The use of explicit numerical, statistical and computational methods to compare languages, infer relationships, estimate change and test historical-linguistic hypotheses.
• Quantitative metathesis — A historical sound change in which adjacent vowels exchange phonological length—classically Ancient Greek long-short sequences becoming short-long while segment order remains fixed.
• Reborrowing — A lexical process in which a form borrowed into another language later returns to its source language with altered form, meaning or usage.
• Rebracketing — A historical linguistic change in which speakers reinterpret the boundary structure of a form into a different sequence of morphemes or words.
• Semitism (linguistics) — A linguistic feature in a non-Semitic text or language attributed to influence from a Semitic source language.
• Sister language — One of two or more languages descended in parallel from the same immediate ancestral language within a historical linguistic family tree.
• Stylometry — Quantitative inference about authorship or style from measured patterns in language or other symbol-producing behavior.
