Social propriety (wypada / nie wypada)

Social Propriety: "wypada" and "nie wypada"

To express what is socially acceptable or expected, Polish uses the impersonal verb wypada (it is appropriate / proper) and its negative form nie wypada (it is not appropriate / proper).

Because they are impersonal, these verbs don't take a subject (like "I" or "you"). Instead, they are followed directly by a verb in the infinitive to state a general rule of etiquette.

For such a ceremony, it is appropriate to come in evening attire.
Na taką uroczystość wypada przyjść w stroju wieczorowym.
During the gala, it is appropriate to pay the host a compliment.
Podczas gali wypada powiedzieć komplement gospodarzowi.

To point out poor etiquette or things that shouldn't be done, use nie wypada.

Generally speaking, it is not appropriate to yawn among the guests.
Ogólnie rzecz biorąc, nie wypada ziewać wśród gości.
This comment was tactless and it is simply not appropriate to speak in this way.
Ten komentarz był nietaktowny i po prostu nie wypada mówić w ten sposób.

Describing Etiquette and Behavior

For formal events, describe behavior and attire with adjectives like stosowny (appropriate) and taktowny (tactful). Form their opposites by adding the prefix nie-: niestosowny (inappropriate) and nietaktowny (tactless).

When we talk with the host, a tactful compliment is always appropriate.
Gdy rozmawiamy z gospodarzem, taktowny komplement jest zawsze stosowny.
Such an inappropriate attire is simply a lack of manners.
Taki niestosowny strój to po prostu brak manier.
