The word "for" comes from Old English "fōr", meaning "for, on account of, because of". It evolved from the Proto-Germanic word "fura".
The word "sure" originated from Old French "seur", derived from the Latin word "securus", meaning "secure, safe, free from care". It can be traced back to the Proto-Indo-European root word "*sekw-", which means "to follow" or "to hold".
Over time, "for sure" emerged as a phrase combining these two words, with "for" indicating a reason or cause, and "sure" emphasizing certainty or assurance. It is commonly used to express confidence or confirm agreement.
