'baccalaurean' originates from Medieval Latin, specifically the word 'baccalaureatus' (from 'baccalaureus'), where 'bacca' meant 'berry' (possibly referring to the laurel berry used symbolically for academic honor).

'baccalaurean' changed from Medieval Latin 'baccalaureatus' and via Old French (as 'baccalauréat') and later English 'baccalaureate' to form the adjective/noun 'baccalaurean' in modern English.

Initially, it referred to matters pertaining to the baccalaureate (the bachelor's degree) and those who held it; over time it has retained this core sense and also specifically denotes a person holding a bachelor's degree.
