in clausum os --> in os clausum

Hello Lilly!
Can I ask you a bridge for evaluation, pls?

"We should already know: loose lips sink ships."

Idiom meaning that unguarded talk may give useful information to the enemy (from WWII)

Thank you, Lilly!
It is not a literal translation, is it? I understand that it is an English equivalent (a source, in fact, because it is originally English) of the Portuguese idiom. Unfortunately I can't remind myself of any Latin proverb that would convey a meaning of the sentence. The closest probably would be: "Loquentia est stultitia loquax" (Verbosity is talkative foolishness?), but it is not exactly the same. So, I think we should translate the idiom literally from Portuguese, just like Alex has done.

Is it: "No flies fly into a closed mouth" or "Fly doesn't come into a closed mouth"?

It's an idiom in both English and Portuguese. From the original, literally:
"Flies don't enter a closed mouth."

Thank you, Lilly.

Hi Alex!
Why did you put the verb "debere" in the conjunctive mode? Is it any reason for that?
debeamus --> debemus?

"in os clausum non init"
this"in" is already included in a verb "inire", so shouldn't be repeated.

And do you think that "quod" is needed here?

Dear Aneta!

1) I wrote "scire debeamus" because "we should know". I think that "scire debemus" means "we must/have to know". Is it wrong?

2) Prefixes! Ok, I will remove the preposition, but why then Cicero used to say "conferre sermonem cum aliquo"?

3) No, "quod" is not needed, I guess.

1) You're right that the verb "debere" is ambiguous one. It may have different meanings: to have to, ought to, should, must... But the mood doesn't change anything.
If you really want to have "should" in Latin it'd be better if you use "Coniugatio Periphrastica Passiva":

"Nobis iam sciendum est" = We should already know

And we don't need to put this "id" either.

2) Haha! Some prefixes have larger functions as "con" does. This is why they don't simply replace prepositions. "Conferre" means "to gather together", "to talk over"... So we have to add the preposition "cum" if we want to say "to talk over with"

3)

I like "Nobis iam sciendum est"

Dzięki!!

Nie ma za co, Alex! Cała przyjemność po mojej stronie. Właśnie zaakceptowałam Twoje tłumaczenie.
