'characteristically-formed' originates from the combination of 'characteristic' and 'formed', where 'characteristic' comes from the Greek word 'kharaktēr', meaning 'a mark or distinctive quality', and 'formed' from the Latin 'formare', meaning 'to shape'.

'characteristic' evolved from the Greek 'kharaktēr' through Latin 'characteristicus', and 'formed' from Latin 'formare', eventually combining in modern English to form 'characteristically-formed'.

Initially, 'characteristic' meant 'a distinctive mark', and 'formed' meant 'to shape', evolving to mean 'formed in a distinctive manner'.
