'characterize' originates from Greek, specifically the word 'kharaktēr,' where 'kharaktēr' meant 'engraver's tool or mark.'

'kharaktēr' transformed into the Latin word 'character,' and eventually became the modern English word 'characterize' through Middle English.

Initially, it meant 'to engrave or mark,' but over time it evolved into its current meaning of 'to describe or define the distinctive nature of something.'
