Oversættelse - Portugisisk brasiliansk-Latin - Para a única pessoa capaz de entender o que sinto.

Efee, great translation!
You chose masculine gender and put feminine version into the remark field, but what do you think if we solve the problem in this way?

Eae personae quae sola...

But "persona" isn't like "person" in English. You know, it means "someone important" or "mask, theatre character"... it isn't the same thing.

Oh, I'm sorry, but I don't agree. We can also use the form in grammatical cases:
prima persona
secunda persona...

Uhm... so let's choose persona.

Nice cooperation with you! We can learn from each other so much! I LOVE
