翻訳 - ブラジルのポルトガル語-フランス語 - Cada um tem de mim exatamente o que cativou...

Oy! This is not very clear, what would it mean exactly? I'm in doubt with "ce qu'il a captivé" :

One can use it at the past "il est captivé par ce qu'il lit en ce moment". Or "cette histoire m'a captivé"

So it would rather be "ce qui l'a captivé" (and for the alternate proposition using the plural form you added in the remarks field, it would be "ce qui les a captivés" than "ce qu'il a captivé" (imho, but I think there isn't enough context to evaluate this translation, I need some more...)

Could you help?

Thanks a lot!

"Each one has from me (exactly/only) what he has captivated"

Does this bridge help?

Yes, it kind of helps...
The way verb "captivate" is used in French being different (see the examples I provided above) does that it has to be in French :
"ce qui [en moi]l'a captivé"

So "Chacun garde de moi ce qui l'a captivé" is the right translation.

I'll edit and validate.

Humm...I think the meaning changes a little.
It's not exactly that.
Let me try to explain...

"captivate" here has the meaning of "conquer"
What the line intends to mean is that each person has to deserve anything s/he wants to have from her, otherwise s/he will not get it.

oh? So use of the French verb "captiver" is inadequate here, actually I think English and French verbs are false friends. it would be better then, according to your explanation, if it were : "Chacun a de moi ce qu'il [en] a conquis"

If you agree, I'll edit with that.
