Names countries use for their First-level subdivisions pro

The plurals are based on the amount of subdivisions that country has. So for example you have to type ''city'' for Uganda because the country only has one first-level subdivision called a city, but you have to type ''cities'' for trinidad and tobago because the country has multiple first-level subdivisions that are called ''cities''. I know it's a bit confusing, but I decided to go with it because it wouldn't make a lot of sense to have plurals for unique administrative entities. for example: in the USA you say states because there are 50 of them, but nobody says federal districts when refering to the capital since there is only one.

for the second point. You are right about the belgian one. I will change the answer to Gewest.

thanks for the constructive feedback :)
