Hei, nach een Lëtzebuerger

How did you come to learn Yenish? was it just for fun or something in life required it?

The part of the city of Luxembourg where I grew up has a history with Yenish (also called Lakerschmus there, meaning language of the ragged people, as in the 19th century many people in that part where trading with rags. How the times have changed...), thus we learned it both organically and some bits at school. Also, some expressions out of the Yenish language have made it into the youth language of Luxembourg, like "Schécks" for girl or "kuff d'Schmul" for shut up.

English and Irish.
