Would just like to check my understanding of お前の持ってる徽章のことで交渉がしたい
Am I correct that the のこと nominalizes "お前の持ってる徽章" and で is simply means 'with' for 交渉がしたい
"With the talisman you have - I want to negotiate"
This こと is not a nominalizer. Nominalization refers to turning a verb/adjective into a noun. It looks like this:
お前の持ってる徽章 is already a noun phrase, and it doesn't have to be nominalized. This ~のこと means "things about..." or "matter regarding...". Please see What is the こと in sentences such as あなたのことが好きだ?
お前の持ってる徽章のことで交渉がしたい。
I want to negotiate with you about/regarding the insignia you have.
Is it grammatical to say お前の持ってる徽章のことを交渉したい
