> Chinese; Arabic; Japanese; Hungarian; Korean; Finnish; Polish Why all well-known Eurasian languages? Lesser-known languages have difficult features galore, especially for European speakers. (The first example which comes to mind is the Papuan language Kalam, which has only ~100 verbs, but uses these to build up precise descriptions of complex actions in a way which is quite difficult for the European speaker to master; but there of course many more examples of difficult-to-learn features like this.)
