'arabella' likely originates from Latin roots, possibly from Late Latin 'orabilis' (from 'orare' meaning 'to pray') or influenced by Medieval/Old French forms of 'amabilis' (from 'amare' meaning 'to love'). Over time these roots contributed to the personal name form.

'Arabella' developed via medieval forms such as 'Orabilis' / 'Amabel' / 'Arabel' or 'Arabelle' in Anglo-Norman and Scots usage and eventually stabilized as the modern English given name 'Arabella'.

Originally associated with meanings like 'lovable' (from 'amabilis') or 'one who may be prayed to' (from 'orabilis'), the literal sense has largely faded and the term is now used primarily as a feminine personal name, often carrying connotations of beauty or loveliness.
