Some words just from memory like my non jewish family used them.
Mesjokke = crazy or crazy about. 'De mazzel' (from mazzeltov)as a salute is still used on a large scale. Gochemerd or gochum for clever.
Not koosher for anything 'fishy'. Today's word came from polish and is transformed through jiddish to the regular english word slob?
It's a partial world language in a way.
