Root Explanation

Uncommonest → It is formed from "un-" (meaning not), "common" (from Old French *comun*, meaning shared by all or usual), and "-est" (a superlative suffix indicating the highest degree). The word "uncommonest" means the least common or the most unusual.

Memory Tip

Think of 'not' ('un-') being added to 'common' to show something that is 'the least usual' — that's what uncommonest means.
