"Matěj hrušky nesmí."

Translation: Matěj cannot have pears.

[dsarkarati]

Would this be acceptable: "Matej must not eat pears."? It seems the meaning is that he is allergic or sensitive in some ways to pears, which can be conveyed by either "He cannot have pears" or "He must not eat pears".

[Trofaste]

It's acceptable and accepted.

This sentence apparently doesn’t need “jíst” as it is obviously implied. But in another exercise, when I translated into Czech “May I eat the last pear?” as “Smím tu poslední hrušku?” it was not accepted without “sníst”. Is there a rule here, or is it that certain specific expressions like this are simply idiomatic and have to be memorized?

[VladaFu]

Well, it is more natural to say "Nesmím hrušky." that means pears in general. But if it is a specific pear, it does not make that much sense, then you should say what you want to do with it.

Got it...thank you.

What about Matej nesmi hrusky

[VladaFu]

I am sure it is accetpted.

[bisousethiboux]

I put "Matej does not allow pears" and it was marked wrong - how would I say that then?

[VladaFu]

Matěj hrušky nepovoluje.

Perhaps you wanted: "Matej is not allowed to have pears"

[on-Rock]

In czech should be: Matěj nesmí jíst hrušky.

[kacenka9]

We do accept such a translation as well, though it is not unusual to just say MUST NOT without indication of what the person must not do with it as it is typically understood.

[JBHayven]

Would you say like that in formal speech or is it rather colloquial? Is it common or limited to some simple contexts, like eating? (I guess also "Matěj nesmí domů" might work, so 'going' would also be covered).
