Abbreviations

 

In General 

The abbreviations “i.e.” (that is) and “e.g.” (for example) are spelled out in running text and notes. Use the abbreviated form in tables, figures, and parentheses.
Note: In McGill, the phrase “See e.g.” is used without a preceding or trailing comma when it begins a sentence.

Other Latin abbreviations, such as “cf ” (compare) and “ca.” (about), are followed by a space.

Capital-letter abbreviations and abbreviations that combine upper- and lowercase letters contain no periods.
