Did you see that last game?

Yeah, it was crazy! The defense was really undefended at times.

Exactly! That made it so easy for the other team to score.

Root Explanation
Undefended → It is formed from "un-" (meaning not) and "defendere" (meaning to defend). The word "undefended" means not defended or lacking protection.
Memory Tip
Think of 'not' ('un-') having 'defense' ('defendere') — that's why undefended means lacking protection.
