'ink' originates from Latin, specifically the word 'encaustum,' where 'en-' meant 'in' and 'kaustos' meant 'burnt.'

'encaustum' transformed into the Old French word 'encre,' and eventually became the modern English word 'ink' through Middle English.

Initially, it meant 'a burnt substance used for writing,' but over time it evolved into its current meaning of 'a colored fluid used for writing or printing.'
