Convert informal English words, phrases, collocations, and sentence fragments into precise TOEFL-appropriate alternatives while preserving meaning and register. Use when a user asks what an expression means, whether it is too informal, how to say it more academically, how to replace low-level vocabulary in TOEFL writing, or how slang/plain English compares with academic alternatives.
