verbargument

Verbargument refers to the nouns, phrases, or clauses that a verb semantically requires or permits in a sentence. In linguistic terminology, these arguments are part of a verb’s valence or subcategorization frame, indicating how many and what types of arguments are possible. The most common categories are the subject or agent, direct and indirect objects, and various complements such as locative, temporal, or instrumental phrases.

Unlike adjuncts, which are optional modifiers, verbarguments are usually obligatory: a transitive verb like “give” typically needs both a direct object (“the book”) and an indirect object (“her”), whereas an intransitive verb like “sleep” requires only a subject. Some verbs have optional arguments (e.g., “eat” can appear with or without an object). Verbargument structure can vary across languages, affecting subject‑auxiliary inversion, passivization, and argument licensing.

In semantics, a verbargument carries thematic roles such as Agent, Patient, Theme, or Experiencer. Syntax and semantics intertwine because argument distribution constrains the possible structures and informs interpretations. Many modern grammatical frameworks, including generative parsing and dependency grammar, model verbarguments explicitly to capture both syntactic dependencies and semantic roles.
