@rin@post.ebin.club @meeper@udongein.xyz its kinda normal for this to happen when cultures split. trade is what polyglots languages and cultures together. when they stop doing that, their shibboleths start to diverge.
irish and scottish galige were in a similar state where they had the same grammar but they chose to use different words for the same things. one called it a pond, the other a lake, same as english dialects do these days.
maybe eastern europeans are just way more violently insistent about their non-differences than everyone else :youmusip:
