I've been interested in learning a language called Malayalam. The problem is though, there is a complete absence of any well-written comprehensive Malayalam textbooks or grammar guides for English-speaking learners of Malayalam. There are some terrible ones written by random people on Amazon, however no real learning resources (except a university course written by the PeaceCorps, which is ok, but only has a limited amount of content). I would start by using basic materials, but the problem is I don't know enough vocab or grammar to work my way through anything, and I can't find a good, reliable, professionally-made English-Malayalam dictionary for reference.
Has anyone else had any experience learning Malayalam, or any language with an absence of learning materials? If so, how did you go about learning it e.g. techniques, learning materials?
