for sure

Absolutely, no question

For sure means definitely or certainly, expressing confident agreement or affirmation: Are you coming tonight? For sure.

It can emphasize certainty: I know for sure he was there.

The phrase often functions as casual confirmation, roughly equivalent to "absolutely" or "yes, definitely." In some contexts it carries a laid-back, especially Californian, tone.
