Morphology

undesirable = desirable (transparent) = un + desire + able

Formed by adding the productive negative prefix 'un-' to 'desirable' (desire + -able), so the meaning 'not desirable' follows standard morphological rules.

Etymology

Undesirable comes from the prefix un- meaning 'not' and the word desire meaning 'want', so it literally means 'not wanted'. It is used for things people do not want because they are unpleasant or harmful.
