@SashSoulsmith@Fantasia1910@ResEvilDude In gendered languages, the pronouns you use are determined by gender. Romance speakers use m. pronouns for Portugal and f. pronouns for Spain. In English, of course, it's traditional to use f. pronouns for all countries, but this is more of an affectation than a rule of grammar.
@stuarthammond14 Some of those are cheating, since they're modern back-formations from place names (Ore from Orford, Alde from Aldeburgh, etc.). But there are rivers with genuinely Anglo-Saxon names, the most prominent one being the Mersey.
@Alex_Fairfax06 I find it unlikely that significant numbers of them would actually pack up and leave if bans like these were passed, but I'd be happy to be proven wrong
