'absinthiate' originates from the word 'absinthe,' which comes from the Latin 'absinthium,' meaning 'wormwood.'

'absinthium' transformed into the French word 'absinthe,' and eventually became the modern English word 'absinthe,' from which 'absinthiate' is derived.

Initially, it referred to the plant 'wormwood,' but over time it evolved into its current meaning of 'to flavor with absinthe.'
