Hardest language to learn. [View all]
Extremely Hard: The hardest language to learn is: Polish Seven cases, Seven genders and very difficult pronunciation. The average English speaker is fluent in their language at the age of 12, in contrast, the average Polish speaker is fluent in their language after age of 16.
Very Hard: Finnish, Hungarian, and Estonian The Ugric languages are hard because of the countless noun cases. However, the cases are more like English prepositions added to the end of the root word. However, anyone arguing Asian languages like Korean trump Uralic languages in complexity, really needs to hit the books and do more research.
Simply Arduous: Ukrainian and Russian Second language learners wrongly assume because these languages use a different script (Cyrillic) that it out ranks Polish. This is not objective, as an alphabet is only lets say 26 letters. It is really the pronunciation and how societies use the language that influences ranking. Ukrainian and Russian complex grammar and different alphabet, but easier pronunciation. (the Poles use a modified Latin alphabet which does not have a neat orthography fit to the sounds of their language). Slavic languages have sophisticated case and gender systems, also something that approximates a complex tense system with aspects of time-verb relationships.
Challenging contender jockey for position: Arabic - Three baby cases which are like a walk in the park compared to the above, but the unusual pronunciation and flow of the language makes study laborious and requires cognitive diligence if you want to speak it.
