The sentence “is this sentence formed what did you do? can you tell me it?” is not grammatically correct in standard English.

What’s wrong with it

  • The word order is unnatural and confusing for a question.
  • The pronoun “it” at the end (“tell me it”) is not used this way in English.

Natural ways to say it

If the intention is to ask whether a sentence is correct and what someone did, more natural versions are:

  • “Is this sentence correct: ‘What did you do? Can you tell me?’”
  • “What did you do? Can you tell me?”

If you want the person to explain their action:

  • “What did you do? Can you tell me about it?”

Quick grammar notes

  • For questions in the past, the structure is: question word + did + subject + base verb → “What did you do?”
  • “Tell me it” is incorrect; use “tell me about it” or “tell it to me” depending on context.

If you share the exact meaning you want (for example: checking a sentence, asking about someone’s past action, etc.), a more precise and polished version can be suggested.
