Root Explanation

Uncrewed → It is formed from "un-" (meaning not) and "crew" (from Old French *creue*, meaning a group of people working together). The word "uncrewed" means not having a crew or group of people aboard.

Memory Tip

Think of 'not' ('un-') having a 'group of people' ('crew') — that's why uncrewed means without a crew.
