Root Explanation

Untruthfulness → It is formed from "un-" (meaning not), "truth" (from Old English "triewð", meaning fidelity or truth), and "-fulness" (meaning the state of being full of). The word "untruthfulness" means the state of not being truthful or lacking in truth.

Memory Tip

Think of 'not' ('un-') being added to 'truth' — this helps you remember that 'untruthfulness' means lacking truth.
