Does Chinese really not have that much grammar though? I think it may have fewer _formalized_ grammar, but there are a lot of rules that are difficult to pin down. And if you don't follow them, your Chinese will sound wrong to native speakers, even though _technically_ the grammar is fine. For example, I only very recently learned (in Mandarin) characters' tones change when they form words. The number one (一) has 3 different tones in different contexts, what!?
