What Is the Difference between "eg" and "ie"?

"Eg" and "ie" are easy to confuse because they are both used to clarify text. However, they are different.

• "Eg" means "for example" (from the Latin exempli gratia).
• I try to eat local sea fish (eg, herring, bass).
(With eg, examples are given for clarification.)
• "Ie" means "in other words" or "that is" (from the Latin id est).
• I try to eat local sea fish (ie, fish caught by boats from my village).
(With ie, a different form of words is given for clarification.)

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).
