*Know your Latin: i.e. vs. e.g.by Ann Edwards
i.e. is the abbreviation of the Latin phrase ‘id est,’ meaning ‘that is.’
e.g. is the abbreviation of the Latin phrase ‘exempli gratia,’ meaning ‘for example.’
Use i.e. when you want to give further explanation for something.
Example: After work I’ll walk over to the Thunderdome, i.e., the new sports arena a few blocks away.
Use e.g. when you want to give a few examples but not a complete list.
Example: I love drinking holiday-related beverages, e.g., hot chocolate, apple cider, pumpkin spice lattes.
