'approachable' originates from the verb 'approach', which comes from the Latin word 'appropinquare', where 'ad-' meant 'to' and 'prope' meant 'near'.

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

Initially, it meant 'to come near', but over time it evolved into its current meaning of 'friendly and easy to talk to'.
