Ukrainian has this thing where the word for with changes the endings of the words that come after it. Those endings have been one of the hardest things for me to nail down in my AI sessions, and I still get corrected on them. But the corrections are coming less often, and some of the endings are starting to feel easier. Here's the part I actually care about. I don't know the rule behind it. I haven't looked it up, and I don't plan to. If I see it enough times, the pattern settles in on its own. That's the whole bet, and watching the corrections drop off without ever opening a grammar book is what keeps me going.
