Root Explanation

Unplanned → It is formed from "un-" (meaning not) and "planned" (from the verb "plan", which comes from Old French *planer*, meaning to devise or arrange). The word "unplanned" means not arranged or devised in advance.

Memory Tip

Think of 'not' ('un-') having a 'plan' — that's why unplanned means something that wasn't arranged beforehand.
