Complete the sentence: She is overwhelmed ___ grief.

Correct preposition usage is crucial for grammatical accuracy. The verb “overwhelm” typically pairs with specific prepositions to convey different meanings. When expressing being overcome by a strong emotion or feeling, the standard and most idiomatic preposition is “with.”

• B. with is the correct choice. The phrase “overwhelmed with grief” correctly conveys that grief is the emotion that has completely overcome her.
• A. of is incorrect; “overwhelmed of” is not a standard English construction.
• C. on is incorrect; “overwhelmed on” is grammatically incorrect in this context.
• D. by is incorrect; while “overwhelmed by” can be used (e.g., “overwhelmed by the waves”), “overwhelmed with” is more commonly used for emotions or abstract concepts like grief.
