'graduate' originates from Latin, specifically the word 'gradus,' where 'gradus' meant 'step' or 'degree.'

'gradus' transformed into the Medieval Latin word 'graduatus,' and eventually became the modern English word 'graduate' through Middle English.

Initially, it meant 'a step or degree in a process,' but over time it evolved into its current meaning of 'a person who has completed a course of study.'
