"Blend of Sarah and Jane"
The name Sarahjane is commonly a female name.
Sarahjane is a compound given name formed from Sarah and Jane, written as one word without a space or hyphen. Both elements are established English-language given names, and the joined form appears in United States birth records from 1938. It is best treated as a combination of two names rather than as a name with a separate etymology of its own.
The pronunciation of Sarahjane is SAIR-uh-jayn.
