Surface Forms

untrue positive

Morphology

untrue = true (semi-transparent) = un + true

Derived from 'true' in the sense 'faithful' (true to someone), but the 'not loyal' meaning is a semantic extension that may not be obvious to all learners.

Etymology

Untrue comes from un- 'not' and true, where true once meant 'faithful' or 'loyal'; it is the same root you see in truth. So to be untrue to someone is to break that faith and not be loyal or honest with them.
