Betina

Betina is a variant of Bettina, itself a diminutive of Elizabeth, which derives from the Hebrew name Elisheba, meaning something along the lines of "my God is an oath" or "my God is abundance." The name gained particular cultural resonance through Bettina von Arnim, the nineteenth-century German Romantic writer and correspondent of Goethe. Related forms include Bettina, Betty, Beth, and the full form Elizabeth, as well as its Italian and Spanish equivalents Elisabetta and Isabel.
