| Were for All Subjects Rule | In formal English, use "were" instead of "was" for all subjects in the IF-clause! | If I WERE rich / If he WERE here |
| No "Would" in IF-Clause Rule | NEVER use "would" inside the IF-clause! Keep "would" exclusively in the main clause. | If I knew his number (CORRECT) vs If I would know his number (WRONG) |
| Hypothetical Unreality Principle | Second conditional describes situations that are OPPOSITE to current reality or highly improbable. | If I were a bird (impossible reality) |
