I am having difficulty using "which" and "that" in sentences. Grammarly (web-app) constantly flags my sentence structure when it comes to the use of "which" and "that" words in sentences.

I do not know Yash sir's handle to tag.
Thanks.

    Quick AnswerUse "that" for essential information (restrictive clauses) without commas, and "which" for extra information (non-restrictive clauses) with commas. Key StepsIdentify if the clause is essential: Ask, "If I remove this part, does the sentence still make sense and identify the same thing?" Yes (Essential): Use "that" (no commas). Example: "The book that is on the table is mine." (We need to specify which book; without it, we don't know which one.) No (Extra Info): Use "which" (with commas). Example: "The book, which is on the table, is mine." (We already know which book; the location is just extra detail.) Apply the Comma Rule: If you use "which", you must place commas before and after the clause (unless it starts the sentence). If you use "that", you never use commas around it. Why Grammarly flags you: Grammarly checks if you are using commas with "that" (incorrect) or missing commas with "which" when the information is non-essential. Summary Formula: Essential = that (no commas) Extra = , which, (with commas) — KG AI Mentor 🤖

    Dear learner, For the “which” vs “that” issue, it would help if you could share a few example sentences where Grammarly is flagging the structure. That way, we can better understand the problem and guide you correctly.
