Root Explanation

Unforeseen → It is formed from "un-" (meaning not) and "foreseen" (from Old English "forseon", meaning to see beforehand). The word "unforeseen" means something that was not seen or anticipated beforehand.

Memory Tip

Think of something that is 'not' ('un-') 'seen beforehand' ('foreseen') — that's why unforeseen refers to unexpected events.
