E.g. vs. I.e.: Meaning, Examples, and Punctuation

Q: What is the difference between e.g. and i.e.?

Use e.g. to introduce one or more examples. Use i.e. to restate, define, or clarify the same idea. The substitution test is direct: try for example for e.g. and that is for i.e.

Q: Does e.g. mean that the examples are the only possibilities?

No. E.g. introduces examples that illustrate the broader statement; it does not identify the examples as the exact equivalent of that statement. Use i.e. when the following words restate or define what came before.

Q: Do I need commas with e.g. and i.e.?

Merriam-Webster notes that e.g. and i.e. are usually followed by a comma. They are also often placed inside parentheses. Because editorial styles can differ, follow the style guide required for your document.

Editorial Sources and Style

The abbreviations come from Latin, but the practical choice is an English substitution test:

e.g. abbreviates exempli gratia and means for example.
i.e. abbreviates id est and means that is.

Merriam-Webster's usage guide to i.e. and e.g. supports both meanings, the substitution test, and the observation that each abbreviation is usually followed by a comma. Its separate Latin abbreviations guide documents the full forms and their functions. These are editorial conventions rather than a claim that every publisher punctuates them identically.
