'resin' originates from Old French, specifically the word 'resine', which came from Latin 'resina', where 'resina' meant 'gum' or 'resin'.

'resina' transformed into the Old French word 'resine', and eventually became the modern English word 'resin' through Middle English.

Initially, it meant 'gum or sticky substance from plants', and this meaning has largely remained the same in modern usage.
