Disclaimer: the last thread I tried to start about language revival got derailed by griping about whether or not endangered and extinct languages should even be revived. If you want to debate that subject, I encourage you to do so in a thread that is not this one. If you do NOT want to learn an endangered, extinct, moribund, or rare language, then please do not post here as it will add nothing to the conversation. Start another thread called ‘People who don’t want to learn weird and possibly useless languages’. If you don’t like learning languages in general, more power to you, but I do not care, so please don’t post about that here.
What counts as a ‘rare, exinct, endangered, or moribund’ language for the purposes of this thread: I am going to use Wikipedia’s Lists of endangered languages and List of extinct languages, not because it is perfect or the last word on the subject, just to have a standard, purely for the purposes of this thread, by which to judge a language’s rareness or deadness. While I understand that you may consider Japanese to be very exotic, it is not in any danger of dying out anytime soon (despite Godzilla’s best efforts to the contrary) and does not count for the purposes of this thread. Sumerian, on the other hand, would.
A resource for those who might wish to know more about endangered languages: Endangered Language Fund.
Phew! Okay, onto the fun stuff. I love language learning, and after I conquer a couple of more well-known languages (French and Turkish) I’d love to learn a rare or extinct language.
One that fascinates me is Michif, a mixed language (as distinct from a creole) that is a combination of French and Cree – the noun phrases are mostly French, and the verbs Cree! C’mon, how cool is that?!
As for extinct languages, I think Hittite is beautiful, and not only is it Indo-European, like my native language English, but it’s, like, all crazy and badass and archaic. Instead of having a masculine/feminine gender system like many of its sibling IE languages, Hittite has inanimate/animate, like some African languages! Besides, if I ever invent a time machine I can travel back to ancient Hattusa and ask for the nearest bar in fluent Hittite (Kuwapi pedan kuedani siessar akuwantari).
