Mastering the Subjunctive Mood: How to Use “Were” in Hypotheticals

Introduction

Have you ever heard a native speaker say, “If I were you, I would study more” and wondered why they didn’t say “If I was you”? This is one of the most common and elegant features of English grammar: the subjunctive mood. Mastering it will make your English sound more natural, precise, and sophisticated. In this post, we will focus on the most important use of the subjunctive: how to use “were” in hypothetical statements and wishes.

What Is the Subjunctive Mood?

The subjunctive mood is a verb form used to express situations that are not real, not certain, or contrary to fact. Unlike the indicative mood (which we use for facts and reality, like “She is a teacher”), the subjunctive deals with wishes, imaginary conditions, suggestions, and demands. The most common subjunctive form in English is “were” used with all subjects (I, he, she, it, they) in hypothetical statements.

For example: If I were rich, I would travel the world. Here, “were” is used even though the subject is “I” — because the situation is not true (I am not rich).

Rules for Using the Subjunctive “Were”

Follow these four simple rules to use the subjunctive mood correctly:

1. Use “were” for all subjects in hypothetical (unreal) conditions. Even with singular subjects like “I,” “he,” “she,” or “it,” we use “were” instead of “was.” Example: If she were here, she would help.
2. Use “were” after “as if” and “as though” for unreal comparisons. Example: He acts as if he were the boss.
3. Use “were” in wishes with “I wish” or “if only.” Example: I wish I were taller.
4. Use “were” in set phrases like “If I were you” (giving advice). This is a fixed expression and always uses “were.”

Important: The subjunctive “were” is only used for unreal or imaginary situations. If the situation is possible or true, use the normal past tense (“was”). Compare: If I was late yesterday, I apologise (possible real past) vs. If I were late, I would miss the bus (unreal hypothetical).

How to Use the Subjunctive “Were” Step by Step

Follow these steps to form correct sentences:

1. Identify the situation: Is it real (fact) or unreal (hypothetical/wish)? If it’s unreal, use the subjunctive.
2. Choose the correct structure:
   • For hypothetical conditions: If + subject + were + complement, subject + would/could/might + base verb
   • For wishes: Subject + wish(es) + subject + were + complement
   • For comparisons: Subject + verb + as if/as though + subject + were + complement
3. Use “were” for every subject (I, you, he, she, it, we, they). Do not use “was.”
4. Check the meaning: Ensure the sentence describes something contrary to current reality.

Example steps:
Step 1: I want to say I am not a bird, but I imagine flying. Unreal? Yes.
Step 2: Use “If + I + were + a bird.”
Step 3: Add the result: “If I were a bird, I would fly away.”

FAQ

1. Is it ever correct to say “If I was”?
Yes, but only when talking about a real past situation. For example: “If I was late yesterday, I apologise” means it is possible that you were actually late. If the situation is hypothetical or unreal (like giving advice), always use “were.”

2. Do I need to use “were” with “he” and “she”?
Absolutely. In the subjunctive mood, “were” is used for all subjects, including third-person singular. So you must say “If he were taller” or “I wish she were here,” not “if he was taller.”

3. What about “if only”? Is it the same?
Yes. “If only” expresses a strong wish and follows the same subjunctive rule. For example: “If only I were younger!” or “If only it were Friday.” Use “were” for all subjects.

4. Can I use the subjunctive with other verbs besides “be”?
Yes, but it’s less common. The subjunctive mood can appear with other verbs in formal English, especially after verbs like “suggest,” “recommend,” or “demand.” For example: “I suggest that he go to the doctor” (not “goes”). However, the most frequent and important subjunctive form for B1–B2 learners is “were.” Focus on mastering that first.
