Ownership for singular nouns is typically shown using an apostrophe followed by the letter "s." Here’s how it works for different cases:
A. For singular nouns: Add an apostrophe and "s" to the noun.
- Example: dog → dog's (the dog's bone)
B. For singular nouns that already end in "s": You can either add just an apostrophe or an apostrophe followed by "s." The choice can depend on style guides or personal preference, but commonly:
- Example: James → James's (James's book) or James' (James' book)
C. For plural nouns that end in "s": Just add an apostrophe after the "s."
- Example: cats → cats' (the cats' toys)
D. For plural nouns that do not end in "s": Add an apostrophe and "s."
- Example: children → children's (the children's playground)
Remember, options may vary based on regional preferences (American English vs. British English) or specific style guides like APA, MLA, or Chicago.
