Stephen Fry touched on some of the quirks of Yinglish this week in his Radio 4 Fry's English Delight, which was about bilingualism. "The Londoners are the only ones who say Shobbes or chollah and motzah," Yiddishist Barry Davis (below) explained. "In standard Yiddish, it is Shabbes, challah and matzah."

And if you want to know why some of us say bygel rather than bagel – Mr Davis is the son of a baker as well as a fluent Yiddish speaker - then you can listen to a clip of their interview on the programme's website.
