Whether we like to admit it or not, we all need reminders sometimes about commonly confused words and phrases. There is no shame in that, and this week we’re here to help you out with “i.e.” and “e.g.” E.g. is an abbreviation for the Latin “exempli gratia,” meaning “for example.” I.e. means “id est,” which is Latin for “that is,” and is used for clarification. Though they may seem similar, the two terms are not interchangeable. However, both are lowercase, have periods and are followed by a comma.
