Apostrophe s vs. s Apostrophe: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on February 29, 2024
Apostrophe s ('s) indicates possession for singular nouns or plural nouns not ending in s, while s apostrophe (s') is used for possessive plural nouns ending in s.
Key Differences
Apostrophe s ('s) is typically used to show possession for singular nouns, indicating that something belongs to or is associated with someone or something. For example, "the cat's toy" implies the toy belongs to the cat. S apostrophe (s'), however, is not used with singular nouns.
S apostrophe (s') is used when the plural form of a noun ends in s and shows possession, like "the dogs' owner" indicating the owner of multiple dogs. Apostrophe s ('s) is not generally used in this context, as it is primarily for singular nouns or plural nouns not ending in s.
The use of apostrophe s ('s) can sometimes affect pronunciation, adding an extra syllable, as in "James's book." In contrast, s apostrophe (s') does not usually change the pronunciation of the plural noun it modifies, as in "students' reports."
There are exceptions and stylistic variations in using apostrophe s ('s), especially with proper nouns ending in s, where practices may vary. For instance, "Charles's guitar" or "Charles' guitar" are both acceptable. S apostrophe (s') usage is more straightforward and follows the general rule for plural nouns ending in s.
The use of apostrophe s ('s) and s apostrophe (s') reflects historical and stylistic preferences in English. Over time, the rules governing their use have evolved, but the fundamental distinction remains based on the singularity or plurality of the possessing noun.
