Etymology
The word is a modern English compound formed by directly combining the Latin prefix 'ex-' with the noun 'student'. The prefix 'ex-', deriving from Latin 'ex' meaning "out of, from," is commonly used in English to denote a former status or a movement away from a previous condition. The noun 'student' originates from the Latin verb 'studēre', meaning "to be eager, to devote oneself to," which entered English via Old French 'estudiant'. Therefore, 'ex-student' logically constructs the meaning of "one who is out of or no longer in the state of being a learner at a specific institution," with the prefix cleanly indicating the cessation of that role.
