'transitional' originates from the Latin word 'transitionem,' where 'trans-' meant 'across' and 'ire' meant 'to go.'

'transitionem' transformed into the French word 'transition,' and eventually became the modern English word 'transition' through Middle English.

Initially, it meant 'to go across or pass over,' but over time it evolved into its current meaning of 'relating to a change or passage from one state to another.'
