"To slovo říkat nesmíme?"

Translation: We cannot say that word?

[Randonneur3]

Interestingly, it becomes an imperative as: 'Can we not say that word?'.

[rejlmen]

Jak se na té větě pozná, že je to otázka (tedy kromě otazniku)? Dík.

[BoneheadBass]

in English, actually, you cannot tell. In writing, the question mark, and in conversation, the intonation, would indicate that it is a question. Otherwise, it could be either a question or a statement.

[CaroleDiva1]

Why not 'We may not say that word', which clearly implies 'we are not allowed to...'?

[VladaFu]

That is accepted. Next time first double-check for any typos and then use "My answer should have been accepted".

[Pollyhs]

we mustn't say that word also shows allowance ( in this case not allowed.)
can we say that for "To slovo říkat nesmíme?
