'Angelina' originates from Italian (and other Romance languages), specifically as a diminutive form of 'Angela', where the root 'angel-' comes from Greek 'angelos' meaning 'messenger'.

'Angelina' developed as a diminutive of Latin 'Angela' (from Greek 'angelos') in Medieval and Renaissance Italian/Spanish usage and was adopted into modern English as the proper name 'Angelina'.

Initially the root meant 'messenger' (Greek 'angelos'); over time the form 'Angelina' came to be used primarily as a female given name, carrying the sense 'little angel' or 'angelic one'.
