'inflammation' originates from Latin, specifically the word 'inflammatio,' where 'in-' meant 'into' and 'flammare' meant 'to set on fire.'

'inflammatio' transformed into the Old French word 'enflamacion,' and eventually became the modern English word 'inflammation' through Middle English.

Initially, it meant 'to set on fire,' but over time it evolved into its current meaning of 'a physical condition characterized by redness and swelling.'
