'triumph' originates from Latin, specifically the word 'triumphus', where 'triumphus' meant 'a public celebration of a military victory'.

'triumphus' transformed into the Old French word 'triumphe', and eventually became the modern English word 'triumph' through Middle English.

Initially, it meant 'a public celebration of a military victory', but over time it evolved into its current meaning of 'a great victory or achievement'.
