Japanese with all the Conichiwas [If that's Japanese. :S and such. [I know I spelled that completely wrong.]
i put chinese even though its not a language. im guessing you meant madrin AND cantonese so thats why i put "chinese" as being harder because theres 2 languages and there are many syllables and stuff. Japanese uses a lot of the syllables from mandrin and cantonese btw.
Japanese, the different ways your say stuff, the ways you gotta order your sayings, the different words if theres a different word infront. But if I wasnt english.. It would MAYBE be English

English is def way up there if it's a second language. I think the various asian languages would also be hard ot leanr, and Greek would also be dificult(not sure if Greeks is what it's called, but w/e)
English is very easy to learn... French and spanish isn't that difficult too... Of all Japonese must be the hardest... Oh I voted others... Try to learn Portuguese. That's difficult I garantee you
