How do you spell chuch face in yiddish?

There is no Yiddish word for "church face." The phrase is English and refers to a facial expression of piety or solemnity that someone might put on when attending a church service, often insincerely.

Yiddish, like other languages, has its own unique ways of expressing similar concepts. If you're looking for a Yiddish equivalent, you'd need to describe the specific facial expression or behavior you have in mind.

For example, you could say:

* "A shpielt a tzeik" (meaning "he's playing a role" or "he's putting on a show") to describe someone acting pious.

* "Er hot a kishkes in a kup" (meaning "he has a bellyache in his head") to describe someone looking miserable or unhappy.

* "A geit mit a shtrengel" (meaning "he's walking with a straight face") to describe someone looking serious or unsmiling.

Ultimately, the best way to express "church face" in Yiddish would depend on the specific context and the meaning you want to convey.
