*In Latin, "eg, ég, .eg, eg., EG, Eg, -eg-, eg- and originally ex. gr." (exempli gratia) means "for example." In an english sentence it is used to introduce an example or list of examples to illustrate what is being discussed.
EXAMPLE: Asia is a large continent, with many large nations (e.g. China, India, and Japan).
*In Latin i.e., an abbreviation of (id est) means "that is; in other words; that is to say."
EXAMPLE: The three U.S. states on the west coast (i.e. Washington, Oregon, and California) have favorable climates.
NOTE: These sound like they could be interchangable but to say [I saw Jasmyn today -- eg, I saw Jenny with a tall, long-haired girl, so I assumed it was Jasmyn.] would be incorrect. It should be i.e. instead of eg to make this sentence correct and sensible.
