Morphology

non-invertible = invertible (transparent) = non + invert + ible

A straightforward negative prefixation: 'non-' negates the adjective 'invertible', yielding 'not able to be inverted'.

Etymology

Non-invertible breaks into non- meaning 'not' and invertible, from invert, a word that means 'to turn'. So a non-invertible thing is 'not able to be turned back', and in math this means it cannot be reversed to get the original.
