‘I.e.’ and ‘e.g.’ are not interchangeable

https://pixabay.com/en/books-notepad-pen-education-690219/When I proofread essays, I often find that these two abbreviations are used as if they mean the same thing. They don’t.

I.e. is the abbreviation for id est. This means ‘that is (to say)’. Use i.e. when you want to introduce another way of putting what you have already written.

E.g. is the abbreviation for exempli gratia. This means ‘for example’. Use e.g. when you want to introduce an illustrative example.

  1. Oh, I am a terrible perpetrator of this! I had not realized that i.e. and e.g. were two different things. I always use i.e. as ‘in example’ haha. Thank you for this insight.

  2. I know that these two mean something different. But remembering what that difference is is tricky. I’ll have to write it down somewhere obvious, I think.
