The Ukrainian language is one of the most widespread languages in the world and takes the 26th place according to the number of its speakers. It is also the second most widespread among the Slavic languages after the Russian language.

The most widely used letter in the Ukrainian alphabet is the letter “п”. It is also with this letter that most of the words start. But the most rarely used letter of the Ukrainian alphabet is the letter “ф”. In the Ukrainian language the words starting with this letter are in most cases borrowed from other languages. The longest word in the Ukrainian language is one of the names of a pesticide:“dichloro-diphenyl-trichloro-methyl-methane”.
