'hallucinogenic' originates from the Latin word 'hallucinari,' meaning 'to wander in the mind,' combined with the suffix '-genic,' meaning 'producing or causing.'

'hallucinari' transformed into the French word 'halluciner,' and eventually became the modern English word 'hallucinate,' from which 'hallucinogenic' is derived.

Initially, it meant 'to wander in the mind,' but over time it evolved into its current meaning of 'causing hallucinations.'
