A straightforward nominalization of the verb 'invert' meaning 'the act or process of reversing', which maps directly onto this general sense.

Etymology

Inversion comes from the Latin invertere, where in- means 'in' and vertere means 'to turn'. So an inversion is a 'turning the other way', like flipping a cake or turning a bottle upside down.
