'platonic' originates from Greek, specifically the word 'Platonikos,' where 'Plato' referred to the philosopher Plato, who emphasized non-physical love.

'Platonikos' transformed into the Latin word 'Platonicus,' and eventually became the modern English word 'platonic' through Middle English.

Initially, it meant 'related to Plato or his philosophy,' but over time it evolved into its current meaning of 'non-romantic or non-sexual.'
