даст: hand

Хӯрокро бо даст мехӯранд.
They eat (their) food with their hands.
Нонро ҳеҷ гоҳ бо як даст нашикан.
Don’t ever break naan (bread) with one hand.

The sentence about not breaking bread with one hand was in a list of good manners. There are a lot of “rules” to do with bread and eating, but that was a new one to me. If you know of other rules or etiquette to do with eating and you want to comment, you can do that below.
