'Angeline' originates from French and other Romance-language usages, specifically related to the name 'Angeline' (a diminutive/variant of 'Angela'/'Angelina'), ultimately from Latin 'angelus' and Greek 'angelos', where 'angelos' meant 'messenger' or 'angel'.

'Angeline' changed from medieval and Romance forms such as the Latin-derived 'Angela' and the Italian/Spanish diminutive 'Angelina', passing through Old French forms and eventually appearing in modern English as 'Angeline'.

Initially tied to the Greek idea of 'messenger' ('angelos'), the word evolved into a proper name evoking 'angelic' qualities; its modern use is primarily as a female given name rather than the original sense 'messenger'.
