Fun Fact with English: Proper use of i.e. etc. and e.g.

So it turns out that "e.g." stands for "exempli gratia," which means for the sake of example, and it indicates the list that follows are examples.

On the other hand, "i.e." is the abbreviation of "id est:" meaning "that is." It indicates a list of possibilities.

"Etc." is short for et cetera (also seen as "&c.") which means "and other things." It indicates "and so forth" or continuation in kind. So it's not considered proper to use etc. to end a list that began with e.g. but you can use it to end a list that began with i.e. Here's why. You don't have endless examples and if you did you wouldn't list them. You'd list an example to get out of having to create an exhaustive list. You could, however, have endless possibilities, in which case you'd want to end it with i.e.

For example: The director gives stage directions (e.g. lights, camera, action).  A Canterbury Tales originally contained several hundred lines in Middle English (i.e. What that aprill with his shoures soote, etc.).

Etc. is occasionally pluralized to create a lofty sounding word meaning "sundries." As in, "We took along pots, pan, and etceteras."
