Firewns: I just published a post: “Dhamma, Sankhara, Sankata, Rupa, Vinnana, Gati, Asava, Anusaya“.
Hopefully, this will answer some of the questions you may still have. Please don’t hesitate to ask further questions. It is important to get these fundamental, but complex, terms clarified. Many people do not really understand these terms, because these words have been badly translated to English.
I have also revised the post: “Difference Between Dhammā and Sankhāra“.
