Mastering Subjunctive Mood: When to Use “Were” Instead of “Was”

Introduction

Have you ever heard someone say, “If I were you, I would take that job,” and wondered why they didn’t say “If I was you”? You are not alone. This is one of the most common points of confusion for English learners, and even native speakers sometimes get it wrong. Mastering the subjunctive mood will help you sound more natural and confident in both writing and speaking, especially when talking about wishes, unreal situations, and polite suggestions.

What Is the Subjunctive Mood?

The subjunctive mood is a special verb form used to express things that are not real, not true, or not certain. It is used for hypothetical statements (things that are imagined or contrary to fact), wishes, demands, and recommendations. Unlike the indicative mood, which states facts (e.g., “He was late”), the subjunctive often changes the verb form. The most famous example is using “were” instead of “was” after words like if, as if, wish, and would rather.

Rules for Using “Were” Instead of “Was”

Here are the key rules to follow when deciding between “were” and “was” in hypothetical statements. Remember: these rules apply to all subjects (I, he, she, it, they, we, you).

1. Use “were” in unreal conditionals (2nd conditional and 3rd conditional): When the condition is impossible, unlikely, or contrary to fact. Example: “If I were taller, I would play basketball.” (But I am not taller.)
2. Use “were” after “wish”: To express a desire for something that is not true. Example: “I wish she were here.” (But she is not here.)
3. Use “were” after “as if” and “as though”: To describe something that seems unreal or imagined. Example: “He acts as if he were the boss.” (But he is not the boss.)
4. Use “were” after “would rather”: To express a preference for an unreal situation. Example: “I would rather you were quiet.” (But you are not quiet.)
5. Use “were” after “if only”: To emphasize a strong wish. Example: “If only it were summer.” (But it is not summer.)
6. Use “was” for factual or real situations (indicative mood): When talking about real past events or facts, use “was.” Example: “He was late yesterday.” (Real event.)

How to Use the Subjunctive “Were” Step by Step

Follow these steps to master the subjunctive “were” in your own sentences:

1. Identify if the situation is real or unreal: Ask yourself: “Is this true, or is it imaginary/contrary to fact?” If it is imaginary, you likely need the subjunctive.
2. Check the trigger words: Look for words like if, wish, as if, as though, would rather, or if only. These often signal the subjunctive mood.
3. Change “was” to “were” for all subjects: Even with “I,” “he,” “she,” or “it,” use “were.” For example: “If I were you…” (Not “If I was you.”)
4. Check the verb tense in the other clause: In conditionals, the clause with “if” uses the subjunctive “were,” and the main clause uses “would” + base verb. For example: “If she were here, she would help.”
5. Practice with common expressions: Memorize fixed phrases like “If I were you,” “I wish I were there,” and “He acts as if he were rich.” This builds automaticity.

Examples in Sentences

• If I were a bird, I would fly to you.
• I wish it were Saturday every day.

Common Mistakes

Even advanced learners make these errors. Here are the most frequent mistakes and how to fix them:

• Mistake 1: Using “was” after “if” in unreal situations.
  ❌ If I was you, I would apologize.
  ✅ If I were you, I would apologize.
• Mistake 2: Forgetting to use “were” with “he/she/it” in wishes.
  ❌ I wish he was here.
  ✅ I wish he were here.
• Mistake 3: Using “were” in a real past event.
  ❌ Yesterday, she were tired.
  ✅ Yesterday, she was tired.
• Mistake 4: Mixing up “as if” + subjunctive with “as if” + real tense.
  ❌ He looks as if he was sick (when he is not).
  ✅ He looks as if he were sick (hypothetical).
  Note: If he actually looks sick, use “was” (real).
• Mistake 5: Overusing “would” in the “if” clause.
  ❌ If I would be taller, I would play.
  ✅ If I were taller, I would play.

Quick Summary

Here is a handy recap of the key points:

• The subjunctive mood is used for unreal, hypothetical, or wished-for situations.
• Use “were” instead of “was” for all subjects (I, he, she, it, we, they) after words like if, wish, as if, as though, would rather, and if only.
• Never use “were” in real past events or facts—use “was” in those cases.
• Common triggers: 2nd and 3rd conditionals, wishes, and unreal comparisons.
• Practice fixed expressions like “If I were you” to build confidence.

FAQ

1. Is it ever correct to say “If I was you”?

In informal, everyday speech, many native speakers say “If I was you,” but it is grammatically incorrect in standard English. For formal writing, exams, and professional contexts, always use “If I were you.” The subjunctive “were” is the correct, traditional form.

2. Do I always use “were” after “wish”?

Yes, when the wish is about a present or future situation that is unreal or unlikely, use “were” for all subjects. For example: “I wish I were taller” (present, unreal). However, when “wish” is used with past perfect (e.g., “I wish I had studied”), that is a different structure for past regrets.

3. Can I use “were” with “if” in real conditionals?

No. In real conditionals (first conditional), use the indicative mood. For example: “If it is sunny, we will go to the park” (real possibility). The subjunctive “were” is only for unreal or hypothetical conditionals (second and third conditionals).

4. What about other verbs in the subjunctive mood?

Great question! Besides “were,” the subjunctive also appears with other verbs, especially after expressions of demand, suggestion, or necessity. For example: “I suggest that he study more” (not “studies”) and “It is essential that she be on time.” The base form of the verb is used for all subjects in these cases.
