Okay kiddo, so you know how some languages use different letters than the ones we use in English? Well, Ukrainian is one of those languages! Instead of using the same letters we have, they have their own special set of letters that they use to write words.
Now, there used to be two different versions of the Ukrainian alphabet - one was called the Cyrillic alphabet and the other was called the Latin alphabet. The Cyrillic one had more letters and was used for a long time, but recently some people in Ukraine wanted to switch to the Latin one because it's used more commonly in the rest of Europe and the world.
The Ukrainian Latin alphabet has 33 letters in it - 26 of them are the same as the letters we use in English, but there are also some extra ones that we don't have. For example, they have a letter that looks like an "i" with two dots over it (it's called "i with diaeresis") and a letter that looks like a "y" with two dots over it (it's called "y with diaeresis").
Overall, the Ukrainian Latin alphabet is just a different way of writing the same language, and some people in Ukraine think it might make it easier to read and write in other languages. So even though it might look a little different from what we're used to, it's still pretty cool!
