Bettina

Bettina is a diminutive form of the Germanic name Bette or Elisabeth, ultimately derived from the Hebrew Elisheba, meaning my God is an oath or my God is abundance. It developed as an affectionate pet form chiefly in German, Italian, Danish, and Hungarian traditions. The name is closely associated with Bettina von Arnim, the 19th-century German Romantic writer and correspondent of Goethe, who helped bring wider literary attention to the form. Related names include Elisabeth, Elizabeth, Betty, and Beth.
