Morphology

impossible = possible (transparent) = im + possible

Direct, productive negation of 'possible' using the negative prefix 'im-', yielding the straightforward meaning 'not possible'.

Etymology

Impossible comes from the parts im- 'not' and possible 'able to be done'. So it literally means 'not able', which is why we use it for something that cannot happen or be done.
