'aethereal' originates from Latin, specifically the word 'aetherius,' where 'aether' meant 'upper air' or 'pure, fresh air.'

'aetherius' transformed into the English word 'aethereal,' maintaining its connection to the concept of the upper air or heavens.

Initially, it meant 'related to the upper air or heavens,' but over time it evolved into its current meaning of 'extremely delicate and light.'
