'eagle' originates from Old French, specifically the word 'aigle', from Latin 'aquila'.

'eagle' changed from Old French 'aigle' into Middle English forms such as 'egle' or 'egle', and eventually became the modern English word 'eagle'.

Initially it meant 'the bird aquila (an eagle)', and over time its use expanded metaphorically (e.g., a person with keen sight) and into specialized senses (e.g., a golf score).
