Tercüme - Brezilya Portekizcesi-Latince - Para o resto de minha vida irei te amar.

In reliquos dies?

Shouldn't this be: "usque in finem" or "usque ad finem", dear Alex?

Well, sincerely I don't know what is the Latin expression for "for the rest of my life". I tried to paraphrase it by saying "for the remaining days of my life". But your suggestion seems much more reasonable

Per omne reliquum vitae tuae tempus ...
Per dies reliquos vitae tuae...

Can I choose "Per omne reliquum vitae tuae tempus" but without "tempus"? Would that be correct?

I don't know too much Portugusese, but I believe that "para" may be an equivalent of Latin "per" in most cases. Am I right?

Hm... "Omne" and "reliquum" describes "tempus", so I'm not sure if it is permissible to leave the word.

Yes I guess your statement is not wrong... I'm not very skilled in Portuguese either, I'm just helped by its resemblance to Italian (and the other Romance languages) and by much conversation with my ex-girlfriend's Brazilian stepmother

Well, if we can't leave it, let's keep "tempus"

Wow, so your mysterious proficiency in so many languages is revealed now! You had got many girlfriends of diferent nations!!! BooHaha!

Hehe, I wish you were right
