About this phrase
Why it works
Kono bepar na literally means "(it's) no matter", using the negator na at the end to dismiss any trouble; the everyday Bangla equivalent of "it's nothing" or "no problem".
Literally
Any matter not
When to use it
A relaxed, gracious reply to "thank you" (dhonnobad); it plays down the favor as no trouble at all. Works with almost anyone.
How it feels
Warm and easygoing.
Formality
Neutral
Grammar
Word by word
The full explanation
A fixed, verbless phrase; Bangla routinely drops 'to be' in the present, so no verb is needed.
kono: any / no; an indefinite determiner, read here as 'no' because of the following na.
bepar: matter / affair / issue; the thing being dismissed.
na: not; the negation particle that turns the phrase into 'it's no matter'.
