Head-Marked Dependency Construction¶
A grammatical construction whose overt relational marker belongs syntactically to the head side of a dependency.
Core Idea¶
A head-marked dependency construction has an overt marker of a grammatical relation on the syntactic head side of a particular construction.[1][2] WALS treats the verb as the clause head relative to its arguments and the possessed noun as the head relative to a possessor.[1][2] The marker may be bound or a separate grammatical word; physical adjacency alone does not determine its syntactic locus.[1][2]
This is a local pattern. WALS calls a language consistently head-marking in its cardinal survey only when both its sampled possessive relation and its direct/primary-object relation are head-marked.[3]
Scope of Application¶
The entry applies to a phrase or clause with an identified head, dependent, relation and overt formative reflecting that relation. Tzutujil verb-borne argument marking and Acoma possessed-noun marking are unlike construction-level positives.[1][2] Tiwi's separate uninflected possessive marker also qualifies because WALS locates it syntactically with the possessed noun in both word orders.[2] One such case does not certify the language's entire grammar.
Clarity¶
First identify the grammatical relation and head/dependent roles; then ask where the relational marker belongs syntactically. In Chechen possession, a genitive on the possessor is dependent marking.[2] In Southern Sierra Miwok, both possessor and possessed noun are marked.[2] The visible marker must be interpreted under the construction's grammatical analysis, rather than its spelling or proximity alone.
Manages Complexity¶
The common locus test compares verb agreement, noun agreement and separate-word markers without treating them as the same form.[1][2] Fijian's nonagreeing possessive suffix shows why agreement cannot be a required genus of every head-marked construction.[2] The local result remains available even when different constructions in one language have different locus types.
Abstract Reasoning¶
Holding the possessive relation fixed, moving its overt marking from the possessed head to the possessor dependent changes the locus classification. Holding the Tiwi formative with the possessed noun while reversing word order does not.[2] Bororo is the decisive near miss: a case-inflected dependent cliticizes headward, yet WALS still classifies its marking as dependent.[2]
Knowledge Transfer¶
The test travels between clauses and possessive phrases when their distinct syntactic roles are declared. Tzutujil and Acoma realize it through different lexical heads and relations.[1][2] It does not automatically travel to whole-language labels or nonlinguistic uses of “head”; those require additional sampling or a different mechanism.
Examples¶
Tzutujil transitive clause. In WALS's example, the verb marks subject and object relations while the displayed argument nouns have no overt marking of those functions.[1] Mapped back: verb head → argument dependents → overt relation marking on verb → head-side locus for that clause.
Acoma possessive phrase. WALS gives a possessed noun agreeing with its possessor noun.[2] Mapped back: possessed-noun head → possessor dependent → possession marking on the possessed head. Tiwi supplies a separate-word boundary case, not a third distinct construction family.[2]

Head-Marked Dependency Construction presupposes Grammatical Relation Domain-specific
Locating a grammatical relation's overt marker on its syntactic head presupposes an analyzed head-dependent relation.
Condition / exception Requires an identified grammatical head-dependent relation and overt relational formative; surface adjacency or phonological host alone cannot establish head locus.

Not to Be Confused With¶
Agreement can realize but does not exhaust the pattern.[2] Double marking marks both members.[2] Headward-migrated dependent marking can put a dependent clitic near a head without moving its syntactic locus.[2] Head-marking language is the broader source title; the frozen member's whole-language, English-diagram, distribution and history branches remain unresolved. The proposed typed graph edge to Grammatical Relation is a strict prerequisite claim: the marker's locus presupposes an analyzed relation, while that relation can exist without head marking.
