'improvement-oriented' originates from the combination of 'improvement' and 'oriented', where 'improvement' comes from the Latin 'improbare', meaning 'to make better', and 'oriented' from the Latin 'orientare', meaning 'to arrange or align'.

'improvement' evolved from the Old French 'emprouvement', and 'oriented' from the French 'orienter', eventually forming the modern English term 'improvement-oriented'.

Initially, 'improvement' meant 'to make better', and 'oriented' meant 'aligned towards'. Together, they evolved to mean 'focused on making better'.
