'admissive' originates from Latin, specifically the word 'admissivus,' where 'ad-' meant 'toward' and 'mittere' meant 'to send.'

'admissivus' transformed into the French word 'admissif,' and eventually became the modern English word 'admissive' through Middle English.

Initially, it meant 'to allow or send toward,' but over time it evolved into its current meaning of 'showing acceptance or willingness to allow.'
