There are also some languages here that are not the most common mother tongue in the country. Latin is no one's mother tongue, and either Italian or German (because of the Swiss Guards) is the most common mother tongue of its residents. Punjabi is the native language of almost half of all Pakistanis, although most of them learn Urdu at some point. Brunei Malay and Tetum Dili are really just dialects of Malay and Tetum, and are certainly closer to their standard dialects than, say, the Arab dialects. Tigrinya should be accepted for Tigrigna, Persian for Farsi, and Azeri for Azerbaijani.
Also, I tried English, French, and Creole... none of which were accepted for Jamaica, etc. Had no idea what you wanted.
I won't list them all but here are a few;
-The most spoken language in Liechtenstein is German
-Persian should be accepted as well as Farsi
-'Brunei' isn't a language (84% speak Malay)
-Tswana should be accepted
-They speak primarily Spanish in equatorial guinea
-Tigrigna is incorrect, should be tigrinya
-French is the most widely spoken language in DRC
-Romanians speak Romanian, not Russian
-Latin is not the most common language in the vatican
I didn't write down all the mistakes, there are a few more.
Otherwise a very good quiz, great effort!!
