'aiery' originates from Middle English, specifically the word 'eyrie,' where 'ey' meant 'egg' and '-rie' was a suffix denoting a place.

'eyrie' transformed into the modern English word 'aiery' through phonetic evolution and spelling variations.

Initially, it meant 'a place where eggs are laid,' but over time it evolved into its current meaning of 'a nest of a bird of prey.'
