'alumnae' originates from Latin, specifically the word 'alumna,' where 'alumnus' meant 'foster child' or 'pupil.'

'alumna' changed from the Latin word 'alumna' and eventually became the modern English word 'alumnae' for the plural form.

Initially, it meant 'foster child' or 'pupil,' but over time it evolved into its current meaning of 'female graduates or former students.'
