Questions & Answers about मैं तुमसे सहमत हूँ।
A word-by-word breakdown is:
- मैं = I
- तुमसे = with you / from you
Here it means with you in the sense of agreement. - सहमत = in agreement / agreed
- हूँ = am
So the structure is basically:
- I + with you + in agreement + am
That is why the full sentence means I agree with you.
Hindi often uses a postposition where English uses a preposition.
Here, से is the postposition attached to तुम:
- तुम = you
- तुमसे = with you / from you / than you, depending on context
With सहमत, Hindi normally uses से to express agreement with someone:
- मैं तुमसे सहमत हूँ। = I agree with you.
- मैं उससे सहमत हूँ। = I agree with him/her.
So तुम alone would not sound correct here. The verb/adjective सहमत requires से for the person you agree with.
