'transition' originates from Latin, specifically the word 'transitio', where 'transire' meant 'to go across'.

'transition' changed from the Middle French word 'transition', which came from Latin 'transitio', and eventually became the modern English word 'transition'.

Initially, it meant 'the act of going across or passing from one place to another', but over time it evolved into its current meaning of 'the process or period of changing from one state or condition to another'.
