“Perhaps the first Shirah was named by a Zionist”
Or – maybe she was born on Shabbos Shira. or maybe her parents are musical. It is still Loshon Kodesh. What is the chiluk?
Shepsel is a nickname form of Shabsai (as in Shabsai Tzvi, which is no doubt a good enough reason not to name someone that). Shabsai in not a Yiddish name, therefore its nickname cannot be based on the Yiddish word for sheep. Shabsai clearly refers to Shabbos and is spelled with a Beis, as opposed to a shepsel which is spelled with a Pei. NO?
