'invert' originates from Latin, specifically the word 'invertere,' where 'in-' meant 'into' and 'vertere' meant 'to turn.'

'invertere' transformed into the Old French word 'invertir,' and eventually became the modern English word 'invert' through Middle English.

Initially, it meant 'to turn into,' but over time it evolved into its current meaning of 'to turn upside down or reverse.'
