Root Explanation

Unknowable → It is formed from "un-" (meaning not) and "know" (from Old English "cnāwan", meaning to know) and "-able" (meaning capable of). The word "unknowable" means not capable of being known or impossible to know.

Memory Tip

Think of 'not' ('un-') being added to 'know' — this helps you remember that 'unknowable' refers to something that cannot be known.
