'adventive' originates from Latin, specifically the word 'adventīvus,' where 'ad-' meant 'toward' and 'venīre' meant 'to come.'

'adventīvus' transformed into the French word 'adventif,' and eventually became the modern English word 'adventive' through Middle English.

Initially, it meant 'coming from outside,' but over time it evolved into its current meaning of 'not native; introduced from another place.'
