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

Introduction

Have you ever found yourself hesitating between “If I was” and “If I were”? You are not alone. This small but crucial grammar choice can make the difference between sounding natural and sounding like a non-native speaker. Mastering the subjunctive mood—especially when to use “were” instead of “was”—is a key skill for B1–B2 learners who want to express wishes, unreal situations, and polite suggestions with confidence.

What Is the Subjunctive Mood?

The subjunctive mood is a verb form used to talk about things that are not real, not certain, or not true at the time of speaking. Unlike the indicative mood, which describes facts and reality (e.g., “He was late”), the subjunctive expresses hypotheticals, wishes, demands, and possibilities.

The most common subjunctive structure you will encounter is the past subjunctive of the verb “to be.” In this mood, we use “were” for all subjects—including singular subjects like “I,” “he,” “she,” and “it.” This is why you see “If I were you” instead of “If I was you.”

Rules for Using “Were” Instead of “Was”

1. Use “were” in unreal conditional sentences (Type 2 conditionals). When the condition is impossible or unlikely in the present or future, use “were” for all subjects. Example: “If she were taller, she would play basketball.”
2. Use “were” after “wish” for present wishes. When you wish something were different now, use “were.” Example: “I wish I were on vacation.”
3. Use “were” in phrases like “as if” and “as though.” These expressions compare reality to something imaginary. Example: “He talks as if he were the boss.”
4. Use “were” in fixed expressions and suggestions. Phrases like “If I were you” or “I’d rather I were somewhere else” always require the subjunctive.
5. Use “was” only when talking about real past events. If the statement refers to something that actually happened or is factual, use “was.” Example: “I was tired yesterday.” (This is real.)

How to Use the Subjunctive Mood Step by Step

Follow these simple steps to decide whether to use “were” or “was”:

1. Ask: Is the situation real or unreal? If it is a fact or something that definitely happened, use “was.” If it is imaginary, unlikely, or contrary to fact, move to step 2.
2. Check the sentence type: Is it a conditional with “if”? A wish? A phrase like “as if”? A suggestion? If yes, you probably need the subjunctive.
3. Look at the subject: For the subjunctive, “were” is used for all subjects (I, he, she, it, you, we, they). Do not change it to “was” even for singular subjects.
4. Test with a reality check: Can you change the sentence to a past fact? For example, “If I were rich” (unreal now) vs. “I was rich last year” (real past).

Example walkthrough: “If I (was/were) a bird, I would fly.” The situation is unreal (I am not a bird), so the correct choice is “were”.

Common Mistakes with “Were” vs. “Was”

Here are typical errors learners make, along with corrections:

• Mistake 1: ❌ “If I was you, I would apologize.”
  ✅ Correct: “If I were you, I would apologize.” (Unreal situation)
• Mistake 2: ❌ “I wish I was taller.”
  ✅ Correct: “I wish I were taller.” (Present wish)
• Mistake 3: ❌ “He talks as if he was the expert.”
  ✅ Correct: “He talks as if he were the expert.” (Comparison to unreal)
• Mistake 4: ❌ “If it was possible, I would travel more.”
  ✅ Correct: “If it were possible, I would travel more.” (Unreal conditional)
• Mistake 5: ❌ “I wish I was there yesterday.” (This is actually correct if referring to a real past event, but often misused.)
  ✅ Clarification: “I wish I was there yesterday” is fine for a real event. But for a present wish: “I wish I were there now.”

Quick Summary

• Use “were” for all subjects in hypothetical, unreal, or wishful statements.
• Use “was” only for real past events or facts.
• Common triggers: if, wish, as if, as though, would rather, suppose.

FAQ

Q1: When should I use “were” instead of “was”?
A: Use “were” in hypothetical, unreal, or wishful situations—even with singular subjects like “I,” “he,” or “she.” For example: “If I were rich” (unreal) vs. “I was rich” (real past). Common triggers include “if,” “wish,” “as if,” and “would rather.”

Q2: Is it ever correct to say “If I was”?
A: Yes, but only in informal English or when talking about a real past possibility. For example: “If I was late yesterday, I apologize.” Here, “was” refers to a real past event. However, for hypotheticals, “If I were” is the standard formal choice.

Q3: What about “I wish I was there” vs. “I wish I were there”?
A: “I wish I were there” is grammatically correct for a present unreal wish. “I wish I was there” is common in everyday speech but is considered informal. For formal writing or exams, always use “were.”

Q4: Do other verbs have a subjunctive form like “were”?
A: Yes, but it is less noticeable. For example, in the subjunctive mood, we say “It is important that he be on time” (instead of “is”) or “I suggest that she go now” (instead of “goes”). However, the most common and tricky one is “were” for the verb “to be.”
