eg and ie

What are the roots of the initials i.e. and e.g.? Is it latin? What do they stand for, and what does it mean?

ANSWER PERSON RESPONDS: “Id est” and “exempli gratia” are derived from their Latin roots. The first, “that is,” is used for “that is to say;” the latter is “by way of example,” used for “for example.” They are often confused, “i.e.,” people use them incorrectly; e.g., “i.e.” is sometimes used when what is really meant is “for example.” Got it?
