A noun is the name of a person, place, thing, or idea.
A noun phrase or nominal phrase (abbreviated NP) is a phrase which has a noun (or indefinite pronoun) as its head word, or which performs the same grammatical function as such a phrase. Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type.
In grammar, a clause is the smallest grammatical unit that can express a complete proposition. A typical clause consists of a subject and a predicate, where the predicate is typically a verb phrase – a verb together with any objects and other modifiers.
An adjective phrase is a phrase whose head word is an adjective, e.g. fond of steak, very happy, quite upset about it, etc. The adjective in anadjective phrase can initiate the phrase, conclude the phrase, or appear in a medial position.
