IPA: //nɒnˈtruːθ//
KK: /nɑntruθ/
Something that is not true; a statement or idea that is false or misleading.
He was caught spreading a nontruth about his colleague.
Nontruth → It is formed from "non-" (meaning not) and "truth" (from Old English "triewð", meaning fidelity or faithfulness). The word "nontruth" means something that is not true or a falsehood.
Think of 'not' ('non-') combined with 'truth' — this helps you remember that 'nontruth' refers to something that is not true.
