Roughly thirty million people in the world speak the Ukrainian language today, mostly in the Ukraine and surrounding regions. It is commonly spoken in parts of Russia, and is very similar to Belarusian, Polish, Russian, Slovak, and Serbo-Croatian according to Wikipedia. Most people who speak Russian can also understand Ukrainian. It is a secondary language in Moldova, Hungary, Serbia, Poland, Romania, Croatia, Slovakia, Bosnia and Herzegovina, and the Czech Republic.
There are four main dialects of Ukrainian, each with unique sub-dialects based upon region and cultural idioms. They are called:
- Northern—also called Polissian: also has three sub-dialects known as Eastern, Central, and West Polissian
- Southeastern: also has four sub-dialects known as Middle Dnieprian, Slobodan, Steppe, and Kuban
- Southwestern: also has eight sub-dialects known as Boyko, Hutsul, Lemko, Podillian, Volynian, Pokkutia (or Bukovynian), Upper Dniestran, and Upper Sannian
- Rusyn—also known as a separate language: has threesub-dialects known as Dolinian or Subcarpathian Rusyn, Pannonian or Backa Rusyn, and Pryashiv Rusyn (the form most commonly spoken in countries such as the United States)
Ukrainian is very similar to other languages as well, such as Belarusian, Daco-Romanian, and Hungarian, so there are many loanwords in each language that are interchangeable. As more people emigrate from the Ukraine, other words are becoming more popular in Ukrainian as well, almost creating new dialects in other parts of the world.
