Often the word is pronounced "ende" because of the Daitshmerizm, so therefore ende sounds like an adjective. It's really a noun though, and often used like your sentence. Also-bizn ende gas, bizn sof vokh, etc.

Pleasure. By the way, I'm under the impression that the word "end" is more for literature use, therefore Yiddishists prefer it. But "ende" I think was more popular in the shtetl life, certainly in Litvish areas according to my research.

Yeah interesting. Could be it depends on the years, like pre-ww1 might be more similar to the folk language as opposed to the later literature which was more perfected based on new Yiddishist takones. I'm personally not involved at all with Yiddish literature, so I wouldn't know. It was just a suggestion...

Actually, what Yiddishists prefer is סוף.

Right, good point. I just meant that the spelling/pronunciation of the word is usually brought as "end" as opposed to "ende", so therefore it's preferred in that regard. But true, the practical use of sof is surely preferred...
