'achievement-oriented' originates from the combination of 'achievement' and 'oriented', where 'achievement' comes from the Old French 'achevement', meaning 'completion', and 'oriented' is derived from the Latin 'orientare', meaning 'to arrange or align'.

'achievement' evolved from the Old French 'achevement', and 'oriented' from the Latin 'orientare', eventually forming the modern English term 'achievement-oriented'.

Initially, 'achievement' meant 'completion of a task', and 'oriented' meant 'aligned towards'. Together, they evolved to mean 'focused on achieving success'.
