Phrase: Definition, Linguistic Properties & Examples

A phrase is a syntactic unit of two or more words that functions as a single grammatical constituent but lacks a subject-predicate structure (unlike a clause).

Key Properties

• Head word – Determines the phrase's category (noun, verb, adjective, adverb, preposition).
• No finite verb – Cannot stand alone as a complete sentence.
• Functional role – Acts as noun, verb, adjective, adverb, or prepositional unit within a clause.

Semantic "Meaning"

In semantics, meaning is the concept, referent, or truth condition conveyed by a linguistic expression. For a phrase, meaning arises from compositionality: the meaning of the whole is a function of the meanings of its parts and their syntactic combination.

Examples

• "kick the bucket" (idiom) – meaning ≠ sum of parts.
• "the cat on the mat" – compositional.

Phrases are the building blocks of sentences; understanding their structure underpins parsing, translation, and NLP.
