My friends and I were talking about what we thought or assumed were the hardest languages, and I had thought it was the branch dealing with Finnish or Hungarian, so I'd heard. And my friends insisted it was Japanese and Chinese because of the many characters. But I was thinking in terms of grammar and what would be difficult to take and apply to our internal, innate structure of language production. From what I've observed, Chinese seems to be very simple in terms of grammar but the real difficulty lies in the memorization of the characters. And though Finnish or Hungarian uses the Roman alphabet, I've heard because of the grammar, these languages are incredibly tough.
Then I am thinking, maybe it was just all pointless to talk about this since, whatever makes a language hard or easy is all entirely subjective and depends on each individual person, where they are coming from in terms of their background, mother-tongue, whether they are bilingual to begin with, whether they are naturally stronger in language skills than others, etc...?
