It has 14 Vowels
English has 5 vowels in it. But Hungarian has almost triple that number. It has the basic ‘a’, ‘e’, ‘i’, ‘o’, and ‘u’. But then there is also á, é, í, ó, ö, ő, ú, ü, ű. The pronunciation of these last 9 vowels changes the meaning of the words so using the correct one is important.
If 14 vowels seem like a lot, consider that Hungarian’s longest word is 44 letters. But they can get even longer because Hungarian is agglutinative which means that stems and affixes can be added to make the words even longer.
