Root Explanation

Undefinable → It is formed from "un-" (meaning not), "define" (from Latin "definire", meaning to limit or determine), and "-able" (meaning capable of). The word "undefinable" means not capable of being limited or determined.

Memory Tip

Think of 'not' ('un-') being added to 'define' which means to limit something, and '-able' means capable of. So, something that is undefinable is not capable of being limited or clearly defined.
