Yes, you can use an apostrophe to indicate possession when writing about someone. The apostrophe is placed before the "s" for singular nouns. For example:
- "Jessica's book" indicates that the book belongs to Jessica.
- "The dog's collar" indicates that the collar belongs to the dog.
If the noun is plural and ends in "s," the apostrophe is placed after the "s." For example:
- "The teachers' lounge" indicates that the lounge belongs to multiple teachers.
- "The cats' toys" indicates that the toys belong to multiple cats.
If the plural noun does not end in "s," you add an apostrophe and "s." For example:
- "The children's playground" indicates that the playground belongs to the children.
So in summary, using an apostrophe to show possession is correct and common in English writing.
