Usage
What’s the difference between i.e. and e.g.? The abbreviation i.e. essentially means that is or in other words—you say it before rephrasing what you’ve just said, often to put it in simpler terms. The abbreviation e.g. essentially means for example—you say it before providing an example of the thing you’ve just mentioned. Both are abbreviations of Latin phrases: i.e. stands for the Latin id est (which literally means “that is”); e.g. stands for exemplī grātiā (which literally means “for the sake of example”). Both are pronounced by saying the two individual letters in the term. Both are commonly used in writing, but i.e. is much more commonly used in speech—most people don’t often say e.g. when speaking (probably because the phrase for example is so common and well understood). Sometimes, people use them in overlapping ways, but this is technically incorrect, since i.e. is meant to indicate a rephrasing, while e.g. is meant to signal that a specific example is going to be given. Of course, both of these things involve an attempt to make what has just been said a little clearer (by clarifying or specifying), so it can be hard to remember when each one is appropriate. To help remember when to use each one, think of the i in i.e. as standing for in other words. Think of the e in e.g. as standing for example (which it pretty much does). Here’s an example of i.e. and e.g. used correctly in the same sentence. Example: The second sewing lesson (i.e., the one starting next week) will cover several different skills (e.g., sewing on a button and sewing a seam). Want to learn more?
