770chabad: You wrote: “Also by pesach besides mah nishtana which is in Yiddish also the simunei haseider”, I think you mean translated in Yiddish. Ma Nishtana is stated in the mishna, long before Yiddish was ever spoken. The simanei haseder are also translated; either RASHI or R’ Shlomo of Falaise were French.
Howevedr, my daughter, was taught in Prospect Park Yeshiva to translate them in French.
