E.g. vs. I.e.

E.g. vs. I.e.

E.g. means “for example,” and i.e. means “in other words.” But both these abbreviations come from Latin. Luckily you only have to remember what they mean in English, not what they stand for in Latin.

But, for the sake of knowledge, here goes.

What do e.g. and i.e. mean?

  • E.g. stands for exempli gratia, which is—you guessed it—an abbreviation of “for example.”
  • How to remember it: “E” is for “Example.”
  • I.e. stands for id est, which means “that is” or “namely.”
  • Memory trick: Another way to translate it is “in essence,” which it also stands for in English.

But why bother with all this Latin? Don’t we have enough abbreviations in English?

Think about it. How would you feel if you got a text message that ended in SWAK? Many of the parents who took a quiz on texting acronyms weren’t sure what it meant. While some teenagers may laugh a little at the older generation’s inability to master texting lingo, the truth is that many of them would be hard-pressed to explain the difference between i.e. and e.g. Now you know the basics, but let’s get into the nitty-gritty of what everyone from student to professional writer needs to know about these meaningful letters.

E.g. Definition

Once again, e.g. is short for exempli gratia, a Latin phrase that means “for the sake of example.” As you may guess, you use it to introduce one or more examples. Don’t worry about listing every possibility; e.g. is used to introduce a few examples, not a complete list.

And now for some examples of e.g.:

Should that happen to poor, as-yet unaffected places (e.g., most of South Asia and Africa) the suffering can be great.

There’s a common view that Malcolm Turnbull’s ‘30-minute city’ is yet another slight variation on the many terms we already have for a more sustainable urban form e.g. compact city, walkable city, smart growth, new urbanism, urban consolidation.
—“Is Turnbull’s ’30-minute city’ a serious election issue?”

I.e. Definition

What about i.e.? A lot of people confuse this expression with e.g., but this one does not have to do with listing examples. I.e.’s Latin origin is the phrase id est, which translates to English as “that is to say” or “in other words.” Here’s a trick to remember this: associate the I of i.e. with the I of “in other words.” Alternately, imagine that the I and E stand for “in essence.”

And now, let’s take a look at i.e. in action:

[What privilege] would allow them to refuse to answer investigators’ questions? Only one: the Fifth Amendment privilege—i.e., the refusal to answer on the grounds that truthful responses might be incriminating.

E.g. and I.e. Examples in a Sentence

First, let’s recap.

E.g. is used to give one or more possible examples. It’s a signal that you’re seeing one or a few of multiple possibilities.

I.e, on the other hand, clarifies; you are providing more precise information. Where e.g. opens up more options, i.e. narrows them down.

Compare these two examples:

After work, I’ll walk over to that new sports arena, i.e., Thunderdome.

After work, I’ll walk over to a sports arena, e.g., Thunderdome or Victory Court.

In the first example, you are clarifying that Thunderdome is the exact arena that you will visit. In the second example, you will visit Thunderdome, Victory Court, or any other sports arena.

Using E.g. and I.e. in Writing

E.g. and i.e. are both lowercase when they show up in the middle of a sentence (i.e., like this).
Most American style guides recommend a period after both letters in both abbreviations.
In general, you add a comma after e.g. and between each subsequent example if there is more than one item in your list.
If you want your examples or your narrowing-down set apart from the rest of the sentence, you can enclose e.g. and i.e., along with the examples associated with them, in parentheses.
Even though exempli gratia and id est are both Latin (and therefore italicized), no need to put e.g. or i.e. in italics when they’re in abbreviated form. Abbrevs are all about keeping things quick and easy, after all.

Now you have a response if a teen teases you about your lack of texting expertise. You can ask her to tell you the words behind some abbreviations that you understand (e.g., id est). FYI (i.e., for your information), SWAK means “sealed with a kiss.”

    Thank you. Q.E.D.

  • Francisco Vianna

    E.g and I.e, I guess, are Latin derived abbreviations used only in written texts, not in current speech. In the case I’m wrong, how should I pronounciate them? With a Latin pronounce or with an English one?

    • As far as I know you say i.e. when reading out loud. At least I do. As for e.g, that is actually changed to few things, but most of them have ‘example’ in the mix. Most common is ‘for example’.

      • Francisco Vianna

        Okay, but how should I pronounce them while speaking in loud voice I.e. (ee ah – in latin way or I.e (I e in saxonic pronounce) and the same for e.g?

        • Angelos TSIRIMOKOS

          Pronounce them the English way [ai i:] and [i: ʤi:]. They are thoroughly assimilated, and no one thinks of them as Latin.
          On the contrary, ‘viz.’, which is a near-synonym of ‘i. e.’, is normally pronounced ‘namely’ 🙂

          • Francisco Vianna

            Interesting and enlightening, From now on I’ll pronounce e.g. in the english way (ee, dzjee). Thanks,

        • i.e. in saxonic. 🙂 I agree with angelos with exchanging e.g. with namely. 🙂
