'approachability' originates from the Latin word 'appropinquare,' where 'ad-' meant 'toward' and 'prope' meant 'near.'

'appropinquare' transformed into the Old French word 'aprochier,' and eventually became the modern English word 'approach' through Middle English.

Initially, it meant 'to come near or closer to,' but over time it evolved into its current meaning of 'the quality of being easy to approach.'
