"Blend of Sarah and Elizabeth"
The name Sarahelizabeth is commonly a female name from the "English" origin.
Sarahelizabeth is a compound given name built from two established names, Sarah and Elizabeth, joined into a single written word. Both elements are long-established English given names that derive from Hebrew: Sarah from the biblical name Sarai/Sarah, and Elizabeth from the Hebrew name rendered in Greek as Elisabet. The joined form has no separate etymology of its own; it works as a double name run together, and it appears in United States birth records from 1983 onward.
The pronunciation of Sarahelizabeth is sair-uh-ih-LIZ-uh-beth.
