Nice work, but the answer for Mozambique should be Portuguese; only 4 million speak Makhuwa. Also Serbo-Croatian is really the language of those Balkan states, so that should be added (and the alternative name Serbo-Croat). Thanks.
So sorry, Mozambique, Serbia, Croatia, Montenegro, Bosnia and Herzegovina, and Uganda are fixed. According to ciaworldfactbook, what I have for Ghana is correct.
Namibia's language should accept alternate names such as Ovambo, Oshivambo, Owambo or even Ambo. Also the Solomon Islands should at least accept Pijin for its language. And please check Poland's and Bulgaria's issues, as previous players mentioned, thanks.
