Non-involved people most definitely cannot understand Yeshivish. A nice example of Yeshivish is the English Yated Neeman, which can be found online at http://chareidi.shemayisrael.com . Many of their articles simply cannot be understood by a non-Jew or a non-Orthodox Jew. That is a simple fact. It is 99% English, but those few Hebrew (and Aramaic and Yiddish) words mixed in make many articles totally unreadable for the average person. I removed the disputed tag. It has been there for months and barely anything was done about the article since, so I presumed it was safe to remove it.  | (talk)
