Use i.e before clarifying or adding to the previous statement.
“I am a vegan, i.e., I do not eat any animal-based products”
- Place a comma before and after “i.e.” This will help the abbreviation stand out and let the reader know you are providing additional information after “i.e.”
- Do not italicize or bold it. The abbreviation “i.e.” does not need to be formatted differently than the rest of the document or paper.
- Lowercase it and use periods. The abbreviation “i.e.” should always appear with a lowercase “i” and a lowercase “e” in a sentence, with a period between both letters.
e.g = exampli gratia = for example = such as
Use e.g before listing examples of the previous statement.
“There are many different flavours of ice cream, e.g., chocolate, vanilla, strawberry.”
- e.g. is usually used in the middle of a sentence and never found at the very end.
- When you use e.g. in a sentence both the letters e and g should be lowercase.
