How's your Latin?
When to use i.e., e.g. and etc. These three Latin abbreviations still appear in modern English and are often confused with one another.
I.e. is the abbreviation of the Latin phrase ‘id est’, meaning ‘that is’.
Use i.e. when you are adding extra information to clarify something that was previously stated. This information is finite, meaning the only possibilities are the things you list after the ‘i.e.’
Example: I am taking two languages this year, i.e. English and French.
