Could I please borrow your pen ? Ans: yeah sure ! Vs Could I please borrow your pen ? Ans: Yeah, for sure!

What's the difference between Sure and For Sure ??!?

I think, sure means - okay And For sure- means certainly

But are there more differences? Which one suits better in the given context ?

  • The only difference I can think of in your exact context is that For sure is more likely to be the response from a non-native speaker (but it''s not a reliable indicator, to be sure). For me at least, the two-word response For sure is usually equivalent to I agree 100% with what you just said. But as an Englishman I'd usually just stick with the one-word form anyway. For sure sounds as "American" to me as To be sure sounds "Irish". Commented Jun 13, 2018 at 13:04

Sure, you can borrow my pen. Conversational.

For sure, you can borrow my pen. Slightly more slangy, also conversational.

For sure has become ubiquitous in American speech. It means the same thing as sure, or yes.
