An adjective phrase (or adjectival phrase) is a phrase whose head is an adjective. Almost any grammar or syntax textbook or dictionary of linguistics terminology defines the adjective phrase in a similar way, e.g. Kesner Bland (1996:499), Crystal (1996:9), Greenbaum (1996:288ff.), Haegeman and Guéron (1999:70f.), Brinton (2000:172f.), Jurafsky and Martin (2000:362). The adjective can initiate the phrase (e.g. fond of steak), conclude the phrase (e.g. very happy), or appear in a medial position (e.g. quite upset about it). The dependents of the head adjective—i.e. the other words and phrases inside the adjective phrase—are typically adverb or prepositional phrases, but they can also be clauses (e.g. louder than you are). Adjectives and adjective phrases function in two basic ways, attributively or predicatively. An attributive adjective (phrase) precedes the noun of a noun phrase (e.g. a very happy man). A predicative adjective (phrase) follows a linking verb and serves to describe the preceding subject, e.g. The man is very happy.
👉 Adjective phrase in the context of English adjectives
English adjectives form a large open category of words in English which, semantically, tend to denote properties such as size, colour, mood, quality, age, etc. with such members as other, big, new, good, different, Cuban, sure, important, and right. Adjectives head adjective phrases, and the most typical members function as modifiers in noun phrases. Most adjectives either inflect for grade (e.g., big, bigger, biggest) or combine with more and most to form comparatives (e.g., more interesting) and superlatives (e.g., most interesting). They are characteristically modifiable by very (e.g., very small). A large number of the most typical members combine with the suffix -ly to form adverbs (e.g., final + ly: finally). Most adjectives function as complements in verb phrases (e.g., It looks good), and some license complements of their own (e.g., happy that you're here).
Adjective phrase in the context of Phrase
In grammar, a phrase—called an expression in some contexts—is a group of one or more words acting as a grammatical unit. For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy". Phrases can consist of a single word or a complete sentence. In theoretical linguistics, phrases are often analyzed as units of syntactic structure such as a constituent. There is a difference between the common use of the term phrase and its technical use in linguistics. In common usage, a phrase is usually a group of words with some special idiomatic meaning or other significance, such as "all rights reserved", "economical with the truth", or "kick the bucket". It may be a euphemism, a saying or proverb, a fixed expression, a figure of speech, etc. In linguistics, these are known as phrasemes.
In theories of syntax, a phrase is any group of words, or sometimes a single word, which plays a particular role within the syntactic structure of a sentence. It does not have to have any special meaning or significance, or even exist anywhere outside of the sentence being analyzed, but it must function there as a complete grammatical unit. For example, in the sentence Yesterday I saw an orange bird with a white neck, the words an orange bird with a white neck form a noun phrase, or a determiner phrase in some theories, which functions as the object of the sentence.
