Surface Forms
Morphology
unbelievable = believable (transparent) = un + believe + able
Formed by adding the productive prefix 'un-' to the adjective 'believable' (itself 'believe' + '-able'), so the negative meaning is directly predictable.
Etymology
The word unbelievable is made of the prefix un- meaning 'not' and believe meaning 'accept as true'. So, something unbelievable is 'not able to be believed', usually because it is very surprising or unlikely.
