The pronoun error in the sentence is with the pronoun "it." The correct analysis and solution are:
- The pronoun "it" should be changed to "the song."
Explanation:
The sentence "After we heard the way he played the song on his guitar, we bought it." has a pronoun error with "it" referring back to "the song." To improve clarity and accuracy, the pronoun "it" should be changed to "the song" to ensure that the reference is clear and specific. This adjustment helps maintain coherence and avoids confusion for the reader by directly linking the pronoun to its intended antecedent.
