'unscorched' originates from the prefix 'un-' meaning 'not' and the word 'scorch' from Middle English 'scorchen', which meant 'to burn slightly'.

'scorchen' transformed into the modern English word 'scorch', and with the addition of the prefix 'un-', it became 'unscorched'.

Initially, 'scorch' meant 'to burn slightly', and 'unscorched' has retained the meaning of 'not burned'.
