Apostrophes
- In Plurals
-
- Don't use apostrophes to form plurals of proper
nouns, acronyms, and numerals. For example, the plural of FAQ is FAQs,
not FAQ's.
-
Don't pluralize single letters, symbols, or mathematical
signs by adding an apostrophe and an s.
-
Incorrect: Salesforce replaces
unrecognizable characters with @’s.
-
Correct: Salesforce replaces
unrecognizable characters with the at (@) sign.
- To form the plural of a numeral, add s but no apostrophe: Type three 2s.
- In abbreviations for measurements, don't
add an s to indicate plurality. For example: 10 oz or 30 mm
- In Possessives
-
- To form the possessive case of singular nouns, including proper
nouns ending in an s or z sound, use an apostrophe followed
by an s.
- To form the possessive of plural nouns, add an apostrophe only.
- Don't use an apostrophe in these possessive pronouns: his, hers,
its, ours, yours, theirs, and whose.
