Syntax: languages
Syntax: language learn (language name)
Languages alone shows which languages you know, and "language learn
(name)" will add to your percentage of language knowledge. To learn a
language, a scholar who is knowledgable in that tongue must be present.
If someone is speaking in a language, and you know it, you will
understand what they are saying. However, to change the language in which
you are speaking, you must change that manually. (See help on SPEAK).
