I see posts describing how an English speaker could learn Spanish, French, and Italian, all together before mastering Chinese.
As a native English speaker I am sure that it is true that some languages such as French and Spanish are much easier for us to learn.
But I feel that compared to non Romance languages, Chinese could be one of the easiest languages to learn for some.
For me I picked up Russian as a third language. I learned the Cyrillic alphabet very, very quickly, probably because my memorization skills have been improved from character memorization. I could read and write and pronounce words with a basic level of proficiency.
But then comes the grammar. Everything is conjucated, verbs, nouns, even pro-nouns! I could not understand how a pro-noun such as Moscow changes with tense (along with the verb).
I don't want to get too long here, what I am driving at is the difficulty in Chinese is clearly in the reading and writing system, but the grammar and thought process of a Chinese person is very close to that of an English speaker; I think of it as caveman English (not at all in a derogatory sense). Just basic clear concise communication.
I think this is something we don't give the Chinese system enough credit for, and in fact discourage people from the language by advertising it as the most difficult in the world.
