Isannah is a very unusual English name and the closest I could find regarding its etymology is that it is most likely a combination of the names Isabel/Isabella (meaning “my God is abundance” or “my God is an oath” from Hebrew) and Susannah (which comes from Hebrew name Shoshannah meaning “lily”; it also means “rose” in modern Hebrew. It may ultimately be derived from Egyptian sšn meaning “lotus”).
Nicknames: Izzy/Izzie, Sanna
Origin: Hebrew, Ancient Egyptian
