'identity-based' originates from the English word 'identity,' which comes from the Latin word 'identitas,' meaning 'sameness,' combined with 'based,' derived from the Old French 'bastir,' meaning 'to build.'

'identity' evolved from the Latin 'identitas' through Old French 'identité,' while 'based' transformed from Old French 'bastir' to the modern English 'base.'

Initially, 'identity' meant 'sameness' or 'being the same,' but over time it evolved to refer to the characteristics that define an individual or group.
