Sorry KBear, but any Yiddish speaker will tell you that Shprintza is the Yiddish word for the season Spring.

Do you mean shprinzin for spring? It is not the source of Shprintza though, like the similarity of Frimet (forgot the source) to the word frum, it could account for the popularity of that name in Eastern Europe, where winters are long, cold and dark.
