Sentences are the basic units of grammar. They consist of various constituents like subjects, objects, adverbials, complements and verbs. Sentences contain different types of phrases including noun phrases, verb phrases, adverb phrases, adjective phrases and prepositional phrases. A sentence is a grammatical unit that contains at least one verb and expresses a complete thought.

11. 1. Noun phrases
A phrase which (typically) has a noun or a pronoun
as its head. It can have various important functions
in a clause or sentence.
(determiner[s]) + (modifier[s]) + noun/pronoun + (modifier[s])

12. 2. Verb phrases
A phrase consisting of one or more verb words. It is
the essential element of a clause.
The verb phrase can also be interpreted as being a
bigger
unit,
including
not
only
verb
constructions, but also the elements of a clause
which follow the main verb such as its object. (Verb
phrase in this sense is equivalent to predicate).

functions are usually recognised to prep. phrases:

2) Acting as adverbials.
