As for putting "e" instead of "i", "o" instead of "u" or similar vowel changes, this can be attributed to the fact that there is no standard way of transliterating Arabic, and local colloquial pronunciations don't always follow standard Arabic phonology.

Because of this, some 'cities' (e.g. St David's, population ~2k) can be significantly smaller than a lot of 'towns' (e.g. Northampton, population ~200k).
People get fussy on other quizzes when the quiz creator calls a 'town' a 'city' and vice-versa, which I think is why QM has chosen to add the quotation marks here.
