Modifier (noun)

A word, phrase, or clause that describes or gives further detail about a noun or verb.

Origin:

Late middle english (as a verb in the sense "qualify, limit"): from old french modifier, from latin modificare "limit, qualify", from modus "measure" + -ficare (from facere "make").

Examples:

1. Adjectives are often used as modifiers to describe nouns.
2. The modifier 'quickly' in the sentence 'She runs quickly' changes the meaning of the verb 'runs'.
3. In the sentence 'The tall man with a red hat', 'tall' and 'with a red hat' are modifiers.
4. Modifiers can be added to sentences to provide additional information.
5. Misplaced or dangling modifiers can change the intended meaning of a sentence.
