I.E. vs. E.G.: Differences and How to Use Correctly

Main i.e. vs. e.g. Takeaways:

  • I.e. means id est. It’s a Latin expression meaning “that is.”
  • Use i.e. when you want to elaborate on a statement.
  • E.g. means exempli gratia. It’s a Latin phrase meaning “for the sake of example” or “for example.”
  • Use e.g. when you want to provide examples to help the reader understand your meaning.

I.e. and e.g. are NOT interchangeable. This quick i.e. vs. e.g. guide covers what these Latin phrases mean, examples of how to use them, and easy steps to look good when you do.

The text "i.e. vs. e.g." appears in dark blue in the middle of the image. To the right is a Roman cartoon character labeled i.e. and to the left is another Roman cartoon character labeled e.g. Both have bronze laurels, togas, and colored sashes.
I.e. is the abbreviation for the Latin term “id est,” while e.g. is the abbreviation for the Latin phrase, “exempli gratia.”

What Does I.E. Mean?

This abbreviation comes from the Latin expression id est, which means “that is.” You can use i.e. to sum up your main point or break down the idea you’re getting at. For instance, use it when you want to rephrase something you just said or to elaborate on something to make your original meaning clearer.

For you to easily remember, just connect the”i” in i.e. to the phrase “in other words.” Meaning, you can use i.e. whenever you could use “in other words.”

We love the great outdoors (in other words, hiking and camping in the mountains).
(Using i.e.)We love the great outdoors (i.e., hiking and camping in the mountains).

Also, since id est roughly translates to “that is” in English, you can also use i.e. whenever you could use “that is.”

Call me if you need anything at all (that is, if you need a ride home from the game.)
(Using i.e.)Call me if you need anything at all (i.e., if you need a ride home from the game.)
A synonym for i.e. is “in other words.”

What Does E.G. Mean?

E.G. is the abbreviation for the Latin phrase exempli gratia. Translated literally, this phrase means “for the sake of example.” What’s more, this is also where we get the more frequently used prepositional phrase“for example.” You can use e.g. anywhere you’d use “for example” or “for instance.”

There’s another simple trick you can use to remember when to use e.g. Connect the “e” in e.g. to the “e” in example.” Then, use the abbreviation when you want to offer an example or multiple examples of something you just mentioned.

I love any kind of desserts with fruit, for example, apple pie, fruit tarts, and cherry turnovers.
(Using e.g.) I love any kind of desserts with fruit, e.g., apple pie, fruit tarts, and cherry turnovers.
She’s taken up several hobbies since retiring last month, for instance, swimming lessons in the morning and gardening in the afternoon.
(Using e.g.) She’s taken up several hobbies since retiring last month, e.g., swimming lessons in the morning and gardening in the afternoon.
A synonym for e.g. is “for example.”
A boy holding two balls. The one on the left is labeled i.e. The one to his right is labeled e.g. To the boy's left side the text reads Use i.e. to elaborate. To his right side, the text reads Use e.g. to give examples.
We use the abbreviation i.e. to elaborate our ideas. On the other hand, we use e.g. to provide examples that would support our ideas.

How Do You Use I.E. or E.G. in a Sentence?

Here are some examples of how to use i.e. in a sentence:

The club offers a full range of VIP perks (i.e., lots of red velvet ropes, free drinks, and seats right by the band).

In this example, i.e. is being used to clarify what the writer meant by VIP perks.

Tanya’s toddler proceeded to put on her very own Broadway show,i.e.twirling in circles as she sang at the top of her lungs.

Here, we’re clarifying that the child’s show isn’t actually a Broadway production. Instead, we use the i.e. as a chance to clarify that the “show” actually was a circle song-and-dance.

English is great, but I prefer more relaxed classes,i.e., recess and lunch.

Here are some examples of how to use e.g. in a sentence:

I use lots of leafy greens (e.g., kale, spinach, and arugula) to make my signature summer salad.
We should use our savings to take a trip somewhere exotic, e.g., Bali or Bora Bora.
I packed all the essentials (e.g., pants, toothpaste, and earplugs), and now I’m ready for my trip.
A cartoon of a young Roman man proclaiming "id est." Above his Laureled head is the text: i.e. or id est means "that is"
Make sure to use the Latin abbreviation i.e. if you want to elaborate on a previously stated idea.

More I.e. vs. E.g. Example Sentences:

Universities in the country (e.g., Harvard, UCLA, and ASU) are close next week for Thanksgiving.
Universities in the country, for example,Harvard, UCLA, and ASU, are close next week for Thanksgiving.

In this example, Harvard, UCLA, and ASU are used as examples of universities.  However, the use of e.g. indicates that all the universities will close down next week, not just the three listed.

Universities in the country (i.e., Harvard, UCLA, and ASU) are close next week for Thanksgiving.
Universities in the country, that isHarvard, UCLA, and ASU, are close next week for Thanksgiving.

In this example, i.e. emphasizes that only three universities in the country will be closed for Thanksgiving.

Are I.E. and E.G. Interchangeable?

Quite the contrary, i.e. and e.g. are NOT interchangeable. While both are abbreviations of Latin phrases, they have different meanings and functions. i.e. means id est, which means “that is” in English. On the other hand, e.g. means exempli gratia, or “for example” when translated to English.

Rules in Using I.E. vs. E.G.

Follow these six grammar rules to make sure you use i.e. vs. e.g. correctly every time:

  1. Capitalize the first letters in i.e. and e.g. if they’re at the beginning of a sentence. Or, if these abbreviations appear in headers (refer to our headers in this article).
  2. Always add a period separating each letter.
  3. Unless they appear at the end of a sentence, always add a comma after the last period.
  4. Offset these abbreviations with commas or parenthesis.
  5. Never italicize these abbreviations.
  6. If you get confused, replace i.e. with “in other words” and e.g. with “for example.

1. How to Capitalize I.e. vs. E.g.

If these abbreviations appear at the beginning of a sentence, in a title, or in a header, you should capitalize the first letter. For example, take a look at the header for this section.

If these abbreviations are in the middle of a sentence and are not part of a title or header, do not capitalize them.

2. Where to Add Periods for I.e. vs. E.g.

Both i.e. and e.g. are abbreviations for full phrases. As a result, we show this by adding a period after each letter of the abbreviation.

Therefore, add a period after the “i” and the “e” in i.e. Similarly, you should add a period after the “e” and the “g” in e.g.

3. When you Need a Comma After I.e. and E.g.

In the same way that you would put a comma after the phrase “in other words” or “for example”, you should add a comma after i.e. and e.g.

This is also due to the fact that both are abbreviations of phrases.

However, there are two exceptions.

A young Roman man saying exempli gratia. The text above his laureled head says: exempli gratia means for example.
If you’re citing examples, make sure to use the abbreviation e.g.

First, you don’t need a comma after either of these abbreviations if it appears at the end of the sentence.

Secondly, you don’t need a comma after e.g.or i.e. if they are not introducing an example of clarification.

For instance, in this article, we discussed both abbreviations as standalone literary devices. In these discussions, you’ll notice that we did not add a comma after each abbreviation.

However, when these abbreviations appear in examples or in action, you’ll notice that we did add a comma after each.

4. Why you Need Commas or Parenthesis with I.e. and E.g.

Although they do it in different ways, both the abbreviations e.g. and i.e. help clarify meaning. In this way, the often add information that helps contextualize or explain.

But, that information isn’t always necessary to the core meaning of the sentence.

As a result, clauses that begin with i.e. or e.g. are usually nonessential or nonrestrictive. This means that if we remove them from the sentence, we might lose some detail but the main idea stays intact.

5. Why you Should Italicize the Phrases, not the Abbreviations

Typically, we italicize Latin words when we use them in English. If you write out id est or exempli gratia, use italics.

However, if you use the abbreviations i.e. or e.g., do not use italics.

6. What to do if you get Confused

If you’re having trouble remembering the difference between i.e. vs. e.g., use this trick:

How to Easily Remember I.e. vs. E.g.:

  • The “i” in “i.e.” stands for “in other words.” Use this one to rephrase of clarify.
  • Thee” in “e.g.” stands for “example” in “for example.” Use this one to give specific examples to illustrate your point.

Incorporate these two abbreviations into your writing, and you’ll be fully demonstrating your literary genius two little letters at a time.
