So in russian, there is such a thing as verb conjuction. Take the word Ходить. If I want to say I walk, the word is Я Ходить. However, the last three letters are ить, and in words like that, you have to change that to a Ю, since Я is behind it. In essence, any word that ends in those last three letters, after Я, has to change to Ю. So we are left with Я ХодЮ
But theres more, Ю cant be used after the letter X due to spelling rules, so we change it to a y. giving us Я Ходy.
And theres more, that word is also subject to consonant mutation, dunno why this happens, it just does, so д is changed to ж. Giving us with the final word Я Хожy.
. Anybody learning Russian has to go through that just to say "I walk". Yeah, thats not messed up at all
