A grammatical term for a word or phrase that modifies another element, such as an adjective modifying a noun or an adverb modifying a verb.
In 'beautiful flower,' 'beautiful' is a modifier.
Too many modifiers make a sentence hard to understand.
被修飾語 is the word being modified, the opposite role of 修飾語.
Compound of 修飾 (modification) + 語 (word). The exact historical derivation is uncertain, but the term is a standard linguistic coinage.
