What does modifier mean?
A modifier is something that changes, limits, or adds detail to another word, phrase, object, or process. Its best-known use is grammatical: an adjective such as “careful,” an adverb such as “quietly,” a noun used attributively, or a prepositional phrase can modify a head word by narrowing or qualifying its meaning. A modifier need not appear immediately before the element it modifies, especially in postpositive constructions. In technical and general contexts, the word can also denote a person or mechanism that adjusts something, or a substance added to a material to alter its properties. The term is precise but somewhat formal outside education and technical writing. It is useful because it distinguishes an element that supplements or qualifies another from one that is grammatically independent or carries the central meaning.

Where does modifier come from?
The noun entered English in the early 17th century through French, ultimately deriving from Latin modificator, meaning “one who modifies.” Latin modificator was formed from modificare, “to alter, change, or limit,” which combined modus, “measure, manner, or limit,” with facere, “to make.” English modify, modification, and modifiable come from the same Latin verb through related borrowing and derivation.
How modifier is actually used
In grammar, modifiers are commonly described as adjectival, prepositional, adverbial, or noun modifiers. Outside specialized contexts, the word can sound formal or impersonal and should not be used as a general substitute for a more precise word such as qualifier, adjunct, or adjusting device.
