What is unclear modifier?

An unclear modifier is a Word, phrase, or clause that is positioned in a sentence in a way that creates ambiguity about what it is modifying. This can lead to confusion or misinterpretation of the sentence's meaning. For example, in the sentence "She almost drove her kids to school every day," the Word "almost" is unclear about whether it modifies "drove" or "every day." To clarify, the sentence should be restructured to specify the intended meaning.
