How to Remember the Difference Between e.g. and i.e.

An easier way to remember the difference between e.g. and i.e. is applying a mnemonic device for the letters in both abbreviations.

For e.g., think of it as “example(s) given.”

For i.e., think of it as “in essence.”

How to Use e.g. and i.e. Correctly

The abbreviations e.g. and i.e. always appear lowercase (yes, both letters) when they appear in the middle of a sentence (i.e., like in this example). Most style guides recommend applying a period after each letter (yes, both letters) in these abbreviations.

parentheses vs brackets a grammar guide via

A comma should be added after e.g. or i.e. (whichever you are using in the sentence) and in between each example when more than one example is listed.

Parentheses can enclose e.g. or i.e. and its examples when you want to set your list apart from the rest of the sentence.

While e.g. and i.e. are abbreviations for Latin phrases, italics are not needed when they appear as abbreviations.
