Synonyms & Antonyms

Root Explanation

Unimpeachable → It is formed from "un-" (meaning not) and "impeachable" (from Latin "impedicare", meaning to entangle or catch). The word "unimpeachable" means not able to be called into question or not able to be accused.

Memory Tip

Think of 'not' ('un-') being added to 'able to be accused' ('impeachable') — that's why unimpeachable means something that cannot be questioned.
