There are some yinglish dictionaries that have been compiled, complete with prefix interfix and suffix modifiers. But the central rule in yinglish is to get meaning across in a communication situation. If your shared memetics of conversation differ, you need to use negotiated approximations until you have the shared vocabulary to settle a topic of discussion.
Not all conversations are cooperative, they can be debates, negotiations, collaborations, or simple chats. The point is, even differing parties need some communal standard to get their message across. That's the goal in yinglish discourse.
Not the Queen's English, not American citiot English. Yinglish, y i n g l ish.
