Identify and correct errors with compound and joint possession
Key Notes
1. Understanding Possession
Possession refers to ownership or the relationship between nouns. There are two types of possession: joint possession and compound possession. Understanding these concepts is crucial for clarity in writing.
2. Joint Possession
Joint possession occurs when two or more nouns share ownership of a single item. In this case, only the last noun in the series receives the possessive form.
a. Structure
- Use ‘s for the last noun to show possession.
- Example:
- Correct: Sarah and John’s project (the project belongs to both Sarah and John)
b. Common Errors
- Incorrect: Sarah’s and John’s project (implies each has a separate project)
- Correct: Sarah and John’s project
3. Compound Possession
Compound possession occurs when two or more nouns own multiple items. Each noun in the compound needs to be possessive.
a. Structure
- Add ‘s to each noun to indicate individual ownership.
- Example:
- Correct: Sarah’s and John’s projects (each has their own project)
b. Common Errors
- Incorrect: Sarah and John’s projects (implies one shared project)
- Correct: Sarah’s and John’s projects
