Morphology

undependable = dependable (transparent) = un + depend + able

The adjective is formed by adding the negative prefix 'un-' to the adjective 'dependable', producing the straightforward opposite meaning.

Etymology

Undependable breaks into un- ('not'), depend ('to hang on' or 'to trust'), and -able ('can be'). Think of something you 'hang' on a person; if it might fall, that person is undependable, so the word means 'not reliable or trustworthy'.
