Morphology

unfirm = firm (transparent) = un + firm

Meaning is directly formed by productive negation prefix 'un-' added to the adjective 'firm', so learners can readily infer 'not firm'.

Etymology

The word unfirm is made of un- meaning 'not' and firm meaning 'strong' or 'solid'. So, unfirm describes something 'not solid', 'loose', or likely to move or change position.
