"eg" or "ie"?

What is the difference between "eg" and "ie"?
  • "Eg" means "for example" (from the Latin exempli gratia).
  • "Ie" means "in other words" or "that is" (from the Latin id est).
If you're unsure whether to use "eg" or "ie," use "for example" (to test for "eg") or "in other words" (to test for "ie"), and you will naturally choose the right one. Remember that "eg" just gives an example or some examples, but "ie" restates the point or spells out the whole list (not just an example).
