'specifically-expressed' originates from the combination of 'specific' and 'expressed', where 'specific' comes from Latin 'specificus', meaning 'pertaining to a species', and 'expressed' from Latin 'expressus', meaning 'clearly presented'.

'Specificus' transformed into the English word 'specific', and 'expressus' became 'expressed' in English, eventually forming the compound adjective 'specifically-expressed'.

Initially, 'specific' meant 'pertaining to a species', and 'expressed' meant 'clearly presented'. Over time, the compound form 'specifically-expressed' evolved to mean 'clearly and explicitly stated'.
