Oversettelse - Brasilsk portugisisk-Latin - A dor é inevitável, o sofrimento opcional.

Traduzir para francês da França.

I have put 'est' at the end of the sentence, because that happens more often in Latin. I have translated optional as 'an option', because I couldn't find the adjective.

<Efylove> The adjective "opcional" is "liber, libera, liberum", but "optio" is a good translation too.
So you can also say: "Dolor inevitabilis, labor liber est".
