'aesthetic' originates from Greek, specifically the word 'aisthētikos,' where 'aisthē-' meant 'perception' or 'sensation.'

'aisthētikos' transformed into the German word 'ästhetisch,' and eventually became the modern English word 'aesthetic' through French influence.

Initially, it meant 'pertaining to perception,' but over time it evolved into its current meaning of 'concerned with beauty or the appreciation of beauty.'
