I.e. and e.g. are two abbreviations that get mixed up quite often.  For some clarification on how to use them properly, this guide will explain a little background on each abbreviation as well as examples that display their usage.

The i.e. and e.g. abbreviations both have their roots in Latin.  The i.e. abbreviation stands for id est in Latin, which translates to “that is” in English.  The e.g. abbreviation stands for exempli gratia in Latin, which translates to “for example” in English.

Now, it may be difficult for you to remember the Latin terms for which these abbreviations stand for, so here is a trick that may come in handy in the future.  I.e. begins with the letter I and essentially means “in other words.”  So, associate i.e. with “in other words” and you should be able to decipher its proper usage.

As for e.g., it starts with the letter E essentially means “for example,” so remember to associate E and “for example” when using the abbreviation.

Using I.e. and E.g.

Since i.e. basically translates to “in other words,” use it when introducing/clarifying something.

Example:

I enjoy playing sports, i.e. baseball and football.

In this example I clarified that baseball and football are the only sports that I enjoy playing.

E.g., meanwhile, translates to “for example,” so you should use it when you are introducing an example.

Example:

I enjoy playing sports, e.g., baseball and football.

Here I just gave examples of sports I enjoy playing.  It does not mean, however, that these are the only sports I like to play.

Remember

When using i.e. and e.g., always remember to put a period after the second letter in each abbreviation.  Using a comma after each abbreviation is good practice, even though your grammar and spell checker will probably say it is an error.  Finally, never italicize i.e. and e.g., as it is not necessary.
