'Angelika' originates from Greek, specifically the word 'angelikos', where 'angelos' meant 'messenger' or 'angel'.

'angelikos' changed into Latin 'angelicus', then into Medieval/Old French forms (e.g. 'angélique') and Medieval Latin 'Angelica', and eventually the modern given name appeared as the variant spelling 'Angelika'.

Initially it meant 'of or pertaining to an angel' (i.e. 'angelic'), but over time the form became used as a personal name meaning a female given name derived from 'angel'.
