Common mistake
Common error with i.e. vs e.g.: "i.e." = complete reformulation (no other options). "e.g." = partial sample (there are more). If Python is just one example: "e.g., Python", not "i.e., Python". Also: never say "i.e." aloud, say "that is" or "in other words".
Trick to remember it
Quick rule
Did you know?
i.e. and e.g. are two of the most confused abbreviations in written English, and the error is made even by educated native speakers. An Oxford English Dictionary survey found that more than 50% of English speakers use them interchangeably or incorrectly. The confusion is so widespread that many scientific journal editors now ask authors to replace "i.e." and "e.g." with "that is" and "for example" to avoid ambiguity. The abbreviations come from Latin: "id est" (i.e. = that is) and "exempli gratia" (e.g. = for the sake of an example). In the original Latin the distinction was perfectly clear; the confusion in modern English demonstrates that opaque abbreviations, by stripping away meaning transparency, favor error.
