My God is an oath
Alizabeth is a modern phonetic variant of the classic name Elizabeth. It ultimately derives from the Hebrew name Elisheva, which combines 'el' (God) and 'shava' (oath). While the 'A' spelling is rare, it retains the deep historical and religious significance of its traditional counterpart.
