What does Aurora mean?
From Latin 'aurora' meaning 'dawn', also the name of the Roman goddess of the morning. Used directly in Italian as both the vocabulary word and the given name.
What does Bella mean?
Directly the Italian/Spanish word bella 'beautiful', from Latin bella/bellus. NOTE: as a given name Bella is most often a short form of Isabella, whose own meaning is 'pledged/devoted to God' (a Hebrew-origin name, NOT beauty); Bella qualifies here only on the strength of the standalone Italian word 'beautiful'.
