People often use e.g. and i.e. incorrectly. The abbreviation e.g. means "for example" and i.e. means "this is to say".

The abbreviation “i.e.” is the shortened form of Latin “id est” which stands for “that is”. This abbreviated sense is mostly used in statements where further clarifications on the notion are necessary.

The abbreviation “e.g.” is also an abbreviated Latin phrase “exempli gratia” which means “For the sake of example”. “e.g.” is mostly used in providing an example to a certain kind of or sort of thing that you are talking about.

Usage of e.g. and i.e.

The following video explains the differences between i.e. and e.g.:

When one talks in a generic or abstract way, more information is sometimes necessary to provide a clear understanding. If one says “I'm going to the place where I work best” the statement leaves ambiguity for a listener who does not know what that place is. So one may further extend the statement as " I'm going to the place where I work best, i.e., the coffee shop". By using "i.e.", one clarifies the meaning of the sentence.

On the other hand if one is talking about a specific kind of entities in a generic way, taking them as a whole, then he will be expected to give an example for his description to make the listeners or readers understand clearly. "At the places where I work best, e.g., Starbucks, I have none of the distractions I have at home". [There are lots of places where I work best; Starbucks is an "example"].

Examples for correctly using i.e. and e.g.

Note that both i.e. and e.g. should be followed by a comma, just like "that is" or "for example" would be. Even though these are Latin abbreviations, there is no need to italicize them because they are so commonly used.
