Root Explanation

Uncertainty → It is formed from "un-" (meaning not) and "certus" (from Latin, meaning sure or certain) and the suffix "-ainty" (derived from the Latin suffix "-antia", indicating a state or quality). The word "uncertainty" means the state of being not sure or lacking certainty.

Memory Tip

Think of 'not' ('un-') being combined with 'sure' ('certus') to remember that uncertainty means the state of not being sure.
