Confusing Words

e.g. vs i.e.

e.g.' and 'i.e.' are both Latin abbreviations used in academic writing, but they do different jobs. 'e.g.' gives examples; 'i.e.' restates the meaning more exactly.

  • e.g. — e.g.' means 'for example'. Use it to introduce examples from a broader group, such as instruments that use the -scope root.
  • i.e. — i.e.' means 'that is' or 'in other words'. Use it to clarify exactly what you mean, not to list examples.

Memory rule: e.g. = for example. i.e. = in other words. If more examples could be added, use e.g.; if you are clarifying the exact meaning, use i.e.
