🧠 5. Essential Grammar Rules
1. Plural Subject Requirement: Reciprocal pronouns require a plural subject or multiple individuals connected by "and" (e.g., say "They helped each other," NOT "Jack helped each other").
2. Action Direction: Make sure the action goes both ways. If person A helps person B, person B must also help person A.
3. Reciprocal vs. Reflexive Difference:
- Reciprocal: "They looked at each other." (A looked at B, and B looked at A).
- Reflexive: "They looked at themselves." (A looked at A in the mirror, and B looked at B in the mirror).
