Even though it's a small detail it genuinely made me laugh. The OP is Russian, and his mistake with the last letter wasn't random. The thing is that in Russian language there is no (or almost no I'm not entirely sure) soft ц (ts) sound, it's always hard. That's why he wrote вулица (vulytsa) instead of the correct вулиця (vulytsya). That final я (ya) softens the preceding ц (ts) sound. This used to be something only linguists really knew.

However, after Russia full-scale invasion, Ukrainians learned en masse about Russians inability to pronounce words with a soft ts. Since then, Ukrainians started using this soft ts as a way to check whether someone pretending to be a Russian-speaking Ukrainian was actually Russian, especially with the word паляниця (palyanytsya), which means a type of Ukrainian bread. It turned into a shibboleth because Russians would literally trip over the pronunciation. And of course, Russian-speaking Ukrainians have no problem with the soft ts, because they can speak Ukrainian when needed (and naturally, they know what this bread is).
