Ibbie

Ibbie is an English diminutive form of Isabel, which itself is a medieval Iberian adaptation of Elizabeth, ultimately derived from the Hebrew name Elisheba, meaning something along the lines of my God is an oath or my God is abundance. It arose as an affectionate pet form used in informal or familial contexts, following the common English practice of creating nicknames through altered initial sounds and the diminutive suffix -ie. Related forms include Ibby, Isabel, Isabella, and Elizabeth.
