CS: “the sources I posted for the Rambams word יכוף- compel, I’d used in relation to convincing with words- those spaces I didn’t compile.”
Maybe it’s just me (or maybe it’s just a typo) but I don’t understand what you’re saying at all.
“I asked a Rav once the question and got the list from him.”
So please ask him again. For my sake.
“Also the Rav said that the contemporary word for convince, ישכנע, isn’t a Lashon Kodesh word.”
But there are other words, such as מפציר, or as the gemoro uses מסרהב.
