'aggie' originates from 'agricultural,' specifically the word 'agriculturalist,' where 'agri-' meant 'field' and '-cultural' meant 'cultivation.'

'agriculturalist' transformed into the colloquial term 'aggie' and eventually became a popular nickname for students of agricultural colleges.

Initially, it meant 'a person involved in agriculture,' but over time it evolved into its current meaning of 'a student or alumnus of an agricultural college.'
