    • Unreal Present / Second Conditional (If+Past Simple→would+base verb\text{If} + \text{Past Simple} \rightarrow \text{would} + \text{base verb}): Used for hypothetical or contrary-to-fact present situations.
      • Example: "If I were you, I would not do that." (Source 1, #238, #294, #438)

    • Unreal Past / Third Conditional (If+Past Perfect→would have+past participle\text{If} + \text{Past Perfect} \rightarrow \text{would have} + \text{past participle}): Used for unreal past conditions and their unrealized outcomes.
      • Example: "I could have helped you if you had been here yesterday." (Source 1, #145)

  • Subjunctive Mood & Mandative Verbs:

    • When verbs or adjectives expressing necessity, requirement, or command are used (e.g., essential, order, require), the dependent clause takes the base verb form (subjunctive mood).
