I searched "Countries in africa that start with the letter K" and got:

While there are 54 recognized countries in Africa, none of them begin with the letter "K". The closest is Kenya, which starts with a "K" sound, but is actually spelled with a "K" sound. It's always interesting to learn new trivia facts like this.

But if I search for "African countries that start with the letter K", I get:

Kenya. Kenya is a country located in East Africa. It shares borders with Tanzania, Uganda, South Sudan, Ethiopia, and Somalia. The country is home to dozens of national parks and reserves and diverse wildlife such as lions, elephants, and buffalo.

It seems to be very specific, but I think that makes it worse.

Edit: I tried the same two, but in Swedish and both yielded a list:

K.

Kamerun.

Kap Verde.

Kenya.

Komorerna.

Kongo-Brazzaville (Republiken Kongo)

Kongo-Kinshasa (Demokratiska republiken Kongo)
