'aesthetically-maintained' originates from the combination of 'aesthetic,' which comes from the Greek word 'aisthētikos,' meaning 'perceptive by feeling,' and 'maintained,' from the Latin 'manutenere,' meaning 'to hold in the hand.'

'aesthetic' evolved from the Greek 'aisthētikos' to the modern English 'aesthetic,' while 'maintain' transformed from the Latin 'manutenere' to the Old French 'maintenir,' eventually becoming 'maintain' in English.

Initially, 'aesthetic' referred to sensory perception, but it evolved to mean 'concerned with beauty or the appreciation of beauty.' 'Maintain' has largely retained its original meaning of 'to keep in a certain state.'
