A phrase is a group of two or more words that make up a grammatical unit.
Modifiers are words, phrases, or clauses that provide additional information about other elements in a sentence. They can describe or limit the meaning of nouns, verbs, adjectives, or adverbs. Modifiers help to add detail and specificity to sentences, clarifying or enhancing the information being conveyed. Examples of modifiers include adjectives (which modify nouns), adverbs (which modify verbs, adjectives, or other adverbs), and prepositional phrases (which can modify nouns or verbs).
