No, they do not speak it! Not all of them. Or, not yet... most of them are just learning it here... (in romanian, papagal is also slang for a nerd or silly guy: "Nu fii papagal" ~= "Don't be silly").
Is there a reason why languages do not use a first capital letter in Romanian?
Hahaha! Well that is a good reply. So I'm assuming they never take capitals then.
and nationalities, etc. In Romanian, the only place where a capital letter is used is the proper nouns and beginning of sentences or titles. English is somewhere in the middle, in this respect, for example Germans capitalize all nouns.
This while nationalities used as adjectives in German are not capitalised either.
I think it's based on the fact that names of languages derive from adjectives. Languages other than English don't have our concept of "proper adjectives".
Why would they? I don't know any language which capitalizes languages besides English or German
