'affluxion' originates from Latin, specifically the word 'affluxio,' where 'ad-' meant 'toward' and 'fluere' meant 'to flow.'

'affluxio' transformed into the French word 'affluxion,' and eventually became the modern English word 'affluxion' through Middle English.

Initially, it meant 'to flow towards,' but over time it evolved into its current meaning of 'the act of flowing towards or into something.'
