text: Like a few people above have said, it depends on what your native language is and how your brain is wired.  Some native English speakers have a real problem with French and German (two languages that should be easy given the similarities to English), but find Mandarin and Japanese easy. It all depends.\n\nFor my money, Finnish is the hardest; in English, we're not very familiar with grammatical cases, which abound in Finnish. Always drove me NUTS!
