Root Explanation

Indefensibility is formed from "in-" (meaning not), "defensibilis" (from Latin, meaning defensible or able to be defended), and the suffix "-ity" (meaning the state or quality of). The word refers to the state of being not able to be defended or justified.

Memory Tip

Think of 'not' ('in-') being combined with 'able to be defended' ('defensibilis') — this helps you remember that indefensibility means the quality of being unable to defend something.
