ECT. = Ectessera

When people use "ect." instead of "etc.", are they doing it on purpose? They couldn't be using ect. as an abbreviation for ectoplasm, which one might be led to think. Is there some word out there that has a similar but slightly different meaning than "et cetera" (meaning: and similar things)? I don't think there is yet, so I'll go ahead and coin a word. It is: ect. = ectessera (ec-tess-uh-ruh), and much more. Now if a person is accused of a typo when using ect., they can just refer others to this post, and then eventually, to the dictionary.
