Traduction - Latin-Suédois - Vir prudens non contra ventum mingit

Singular

Yes, I know the English version comes in singular, but this is a Latin quote usually translated in plural into Swedish.

"Visa män urinerar inte i motvind"

OK, I just thought that "vir" is singular
Shall I change it back??

It is singular, indeed.
What I mean is that quotes aren't always translated using the 'exact' words.
Both translations are correct, but quotes sometimes become more popular in a version that is not exactly a word-by-word translation.
You must know better how this 'saying' is known in Swedish.
In Portuguese, for example, the translation of it is not as "polite" and the term used for "urinate" is more vulgar.
Instead of the literal translation:
"Um homem sábio não urina contra o vento" it would be:
"Quem é esperto não mija contra o vento"

See what I mean?

Aha! Then there is a more "vulgar" way to put it in Swedish too. But it's more like an advise: Man ska inte pissa i motvind. There is also a similar: Man ska inte spotta i motvind. Nothing about wise men there!

Yeah, we have that one with "spotta" too, but we say "Se cuspir pro alto vai te cair na cara" (If you split upwards it will fall on your face)
