I’m doing a concept note for Lesotho at the moment. Learning how to describe anything has been a little confusing. If you’re ever writing about the place or just looking to impress please consult the following (though as always I could be wildly wrong)
1. A single person from Lesotho is Mosotho. (So for example Mark is Irish, Makhetha is Mostotho)
2. Multiple people from Lesotho are Basotho (Mark and David are Irish, Makhetha and John are Basotho)
3. The adjective is also Basotho (so the Basotho flag, the Basotho context etc)
4. The language is Sesotho
5. And as far as I can make out the word ‘Lesothian’ doesn’t exist.
