for sure

Certainly, without doubt; also, I agree. This seemingly modern phrase dates from the late 1500s, at least in the first sense. John Milton used it in Paradise Regained (1671), “Now, now, for sure deliverance is at hand.” The second sense is somewhat more recent, and is often put as that’s for sure. C. Bonington had it in Annapurna South Face (1971), “We can’t do it in the next two days.—That’s for sure.”
