'aigret' originates from French, specifically the word 'aigrette,' where 'aigre' meant 'sharp' or 'pointed,' referring to the shape of the feathers.

'aigrette' transformed into the English word 'aigret' and eventually became the modern English word 'aigret' through Middle English.

Initially, it meant 'sharp or pointed feathers,' but over time it evolved into its current meaning of 'a decorative plume.'
