Bette

Bette is an English diminutive of Elizabeth, which traces back through Latin and Greek to the Hebrew name Elisheba, meaning my God is an oath or my God is abundance. It developed as a pet form alongside Betty and Beth and gained independent use as a given name in its own right. The actress Bette Davis, born Ruth Elizabeth Davis, helped establish the form as a recognized standalone name in the twentieth century. Related forms include Beth, Betty, Betsy, and Eliza.
