Root Explanation

Unkillable → It is formed from "un-" (meaning not) and "kill" (from Old English "cwellan", meaning to cause to die) and "-able" (meaning capable of). The word "unkillable" means not capable of being killed or unable to die.

Memory Tip

Think of 'not' ('un-') being combined with 'cause to die' ('cwellan') and 'capable of' ('-able') — this helps you remember that unkillable means something that cannot be killed.
