Estonian uses the Roman alphabet, like English, with the addition of letters like õ, ä,ö, and ü. It has 14 noun cases along with short and long consonants and vowels, which explains why it has been named the world's 5th hardest language to learn for English speakers after Japanese, Chinese, Korean and Arabic. It would take an estimated 1,100 class hours to reach proficiency. Learners will be relieved to know, however, that Estonian has no gender or future tense. It does have plenty of tongue twisters and it's possible to build dizzyingly long compound words, like the 24-letter long kuulilennuteetunneliluuk. It means "the hatch a bullet flies out of when exiting a tunnel" and is also a palindrome.
