I love both the sound and meaning of
Shayna. It's sometimes spelled
Sheine and
Jeanette or
Jane were often used as anglicised approximations of it by girls from Yiddish-speaking families.
In Hebrew the equivalent in meaning is
Yaffa.
There's a variant, Shayndel (Sheindel), the name of someone I know.
Shani means "scarlet" in Hebrew and evokes the legend of the "scarlet thread".
I love
Shayna.
