A restrictive phrase is necessary to the meaning of a sentence

A phrase is a group of related words standing together as a single unit that needs to be part of a sentence or a clause to mean something. There are several types of phrases, such as noun phrases, gerund phrases, participial phrase, among others. Now, these phrases can be a restrictive phrase or nonrestrictive.
