My Chinese teacher keeps repeating this grammar rule of “First Say, First Do” and I keep saying, but I don’t understand what that means. Then she says, “You must learn this. It’s very important in Chinese.” But what the heck does it mean? Today we were doing sentences like "Wo3 Qing3 Ta1 Chi1 Fan4 (I invited/will invite him to dinner) And she keeps saying “First Do, First Say.” It makes no sense to me whatsoever. I can see a do-I invited, but where does the say come in, and how does this help me understand the word order in a Chinese sentence? :?
Can anybody shed some light on what she is trying to tell me?
