'immediately' originates from Latin, specifically the word 'immediatus,' where 'in-' meant 'not' and 'medius' meant 'middle.' 'Finished' comes from the Old French 'finir,' meaning 'to end or complete.'

'immediatus' transformed into the Old French 'immediat,' and eventually became the modern English word 'immediate.' 'Finir' evolved into the Middle English 'finisshen,' leading to the modern English 'finish.'

Initially, 'immediate' meant 'without anything in between,' and 'finish' meant 'to bring to an end.' Over time, 'immediately-finished' evolved to mean 'completed without delay.'
