Betty

Betty is an English diminutive of Elizabeth, which itself traces back through Latin and Greek to the Hebrew name Elisheba, meaning something along the lines of my God is an oath or my God is abundance. The name gained wide popularity as a standalone given name in the twentieth century, particularly in the United States, where it ranked among the most common names for girls during the 1920s and 1930s. Notable bearers include American activist Betty Friedan and actress Betty Davis, helping cement the name's association with that mid-century era. Related forms include Beth, Bette, Betsy, and Eliza.
