Here's why this is a problem:
* Clarity: Pronouns are meant to be efficient shortcuts, referring back to something already mentioned. If the reader can't figure out what "it," "they," or "he" is referring to, the writing becomes confusing and unclear.
* Misinterpretation: Without a clear antecedent (the noun or phrase the pronoun refers to), the reader might misinterpret the meaning. This can lead to misunderstandings and even unintended humor.
Here's an example of ambiguous pronoun reference:
"The dog chased the cat, and it ran up the tree."
What's unclear? We don't know if "it" refers to the dog or the cat.
How to fix it:
* Be specific: "The dog chased the cat, and *the cat* ran up the tree."
* Rewrite for clarity: "The dog chased the cat. The cat ran up the tree."
Remember: Clear pronoun reference is essential for effective communication. Always make sure your pronouns have clear and unambiguous antecedents.
