sure
Free from uncertainty
Sure expresses certainty or confidence.
If you're sure of something, you have no doubt: I'm sure she said Tuesday.
As an affirmation, sure means yes: Can you help me? Sure.
This casual use can sound grudging or unenthusiastic compared to stronger affirmatives.
Sure also intensifies: It sure is hot today.
A sure thing is guaranteed to succeed.
Make sure means verify or ensure.
