'graduate' originates from Latin, specifically the word 'graduatus,' where 'gradus' meant 'step' or 'degree.' 'Related' comes from Latin 'relatus,' meaning 'brought back.'

'graduate' changed from the Latin word 'graduatus' and eventually became the modern English word 'graduate.' 'Related' evolved from the Latin 'relatus' through Old French 'relater.'

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