   Format: MarkdownItexIf this entry is about formal languages, as it is now, then in my opinion it better be called [[formal language]] and [[language]] should be a separate entry (for disambiguation to start); I can divide this way if you like the idea. Notice that we also have entries [[linguistics]] and [[mathematical education]] about the subjects where other kinds of languages are also of concern, not to mention interesting subjects like quantum information also needing wider scope. $n$Lab is envisioned to include physics, mathematics and philosophy and for philosophers at least, and to many kinds of physicists the language of concern and consideration is as well not only the formal language.
