I have attended a few traditional masses in Latin. My proposal is to learn the language by reading the bilingual prayers and Bible readings. Since I can already read Spanish and French, I have been able to fill in most of the gaps. However, can I truly learn Latin this way without formally studying its vocabulary or grammar rules? What about more foreign languages like Sanskrit, Aramaic or Hittite?
I want to be able to open up any page in any book written in said dead language and at least get the general gist.
