When you mean â€œfor example,â€ use e.g. It is an abbreviation for the Latin phrase exempli gratia. When you mean â€œthat is,â€ use â€œi.e.â€ It is an abbreviation for the Latin phrase id est. Either can be used to clarify a preceding statement, the first by example, the second by restating the idea more clearly or expanding upon it. Because these uses are so similar, the two abbreviations are easily confused. If you just stick with good old English â€œfor exampleâ€ and â€œthat isâ€ you wonâ€™t give anyone a chance to sneer at you. If you insist on using the abbreviation, perhaps â€œexample givenâ€ will remind you to use â€œe.g.,â€ while â€œin effectâ€ suggests â€œI.E.â€
Since e.g. indicates a partial list, it is redundant to add â€œetc.â€ at the end of a list introduced by this abbreviation.
