A modifier is a word, phrase, or clause that describes or qualifies another element in the same sentence. For example, in the sentence "She slept for eight hours," the word "for" is a modifier that describes how long she slept.
Here are some other examples of modifiers:
- verbal modifiers: almost, mostly, partially, etc.
- adjectival modifiers: big, small, red, etc.
- adverbial modifiers: slowly, quickly, yesterday, etc.
Modifiers can be placed in different positions within a sentence, depending on what they're describing. For example, if a modifier is describing a noun, it will usually come either before or after the noun. If it's describing a verb, it will usually come after the verb.
