What are the rules for using reflexive pronouns as objects in grammar syntax?

The rules for using reflexive pronouns as objects in grammar syntax are as follows:

1. Reflexive pronouns are used when the subject and the object of a sentence refer to the same person or thing. For example: "She cut herself while cooking."

2. Reflexive pronouns are formed by adding "-self" (singular) or "-selves" (plural) to the appropriate personal pronoun. For example: "myself," "yourself," "himself," "herself," "itself," "ourselves," "yourselves," "themselves."

3. Reflexive pronouns are used to emphasize the subject's action on itself or to show that the subject is performing an action on itself. For example: "I taught myself how to play the guitar."

4. Reflexive pronouns can also be used for emphasis or to avoid ambiguity. For example: "The president himself addressed the crowd."

5. Reflexive pronouns are not used as direct objects when the action is performed by someone or something else. For example: "She washed the dishes herself" (correct) vs. "She washed herself" (incorrect).

6. Reflexive pronouns are not used after certain verbs that do not indicate an action performed by the subject on itself. For example: "He enjoyed himself at the party" (correct) vs. "He enjoyed at the party" (incorrect).

7. Reflexive pronouns are not used after prepositions unless the action is performed by the subject on itself. For example: "She bought a gift for herself" (correct) vs. "She bought a gift for her" (incorrect).

It is important to follow these rules to ensure proper usage of reflexive pronouns in grammar syntax.
