This document discusses pronouns and common issues that ESL/EFL students have with them. It defines different types of pronouns like personal, reflexive, reciprocal, possessive, indefinite and demonstrative pronouns. It also explains anaphora and how pronouns relate to their antecedents. Common errors students make involve choosing the wrong pronoun form, transferring rules from their native language, and modifying antecedents. The document suggests teachers be aware of how a student's first language may interfere with English pronouns and diversify activities to help students learn.
