Bettie

Bettie is an English diminutive form of Elizabeth, which itself derives from the Hebrew name Elisheba, meaning my God is an oath or my God is abundance. It developed as a familiar pet form alongside Betty, both of which gained widespread independent use as given names in the English-speaking world. The name is associated with American pin-up model Bettie Page, who brought particular visibility to the spelling in the twentieth century. Related forms include Beth, Bess, Bessie, Betsy, Betty, and Eliza.
