To keep you from being confused, here are some abbreviations and their usages.
This is an abbreviation for Latin words meaning “For example.”
It is usually followed by a comma and should not be confused with “i.e.”
Example: “The magazine article covered many topics, e.g., getting started, completing the work and submitting the piece to editors.”
This is an abbreviation for the Latin words meaning “that is.”
Most often followed by a comma and is not to be confused with “e.g.”
Example: “At that hour, Mr. Jones was usually indisposed i.e., taking his afternoon nap.”
I hope this helps.
