Introduction
Have you ever stopped mid-sentence, wondering whether to say “If I were” or “If I was”? You are not alone. This is one of the most common grammar questions for English learners at the B1–B2 level. Getting it right can make your English sound more natural, confident, and correct. In this post, we will explore the subjunctive mood—what it is, when to use it, and how to choose between “If I were” and “If I was” with ease.
What Is the Subjunctive Mood?
The subjunctive mood is a special verb form used to express wishes, hypothetical situations, suggestions, or demands. It is not about facts—it is about possibilities, desires, or things that are not true. In modern English, the subjunctive mood appears most often with the verb “to be.” Instead of saying “I was,” we say “I were” in certain situations. This is the key to understanding the difference.
Think of the subjunctive as the “unreal” mood. When you say “If I were a bird,” you are imagining something that is not real. When you say “If I was late,” you are talking about a real past event. That distinction is everything.
Rules for Using “If I Were” vs. “If I Was”
Follow these numbered rules to decide which form to use.
- Use “If I were” for hypothetical or unreal situations. These are things that are not true, impossible, or imagined. Example: “If I were taller, I would play basketball.” (You are not taller.)
- Use “If I were” for wishes. When you express a desire for something that is not true, use the subjunctive. Example: “I wish I were on vacation.” (You are not on vacation.)
- Use “If I were” for suggestions or advice. In phrases like “If I were you,” always use “were.” Example: “If I were you, I would study more.”
- Use “If I was” for real past events. When you talk about something that actually happened or was true in the past, use the indicative mood. Example: “If I was late yesterday, I am sorry.” (You were actually late.)
- Use “If I was” for factual conditions. When the condition is likely or true, use “was.” Example: “If I was in the kitchen, I probably made coffee.” (You were in the kitchen.)
How to Use the Subjunctive Mood (Step by Step)
Follow these steps to master the subjunctive mood:
- Identify the sentence type. Ask yourself: Is this a real situation (fact) or an unreal situation (hypothetical, wish, or imagination)?
- Check the verb “to be.” If the sentence uses “I” or “he/she/it” with “if” or “wish,” decide if you need the subjunctive.
- Apply the rule: For unreal situations (impossible, imagined, or wished), use “were” for all subjects (I, he, she, it). For real past situations, use “was” for I, he, she, it.
- Test with a replacement. Try replacing “I” with “he.” If you would say “If he were” (unreal), then use “were.” If you would say “If he was” (real past), use “was.”
- Practice with common phrases. Notice fixed expressions like “If I were you” or “I wish I were.” These are always subjunctive.
Example step: Sentence: “If I ___ the president, I would lower taxes.” Is this real? No, you are not the president. So use “were”: “If I were the president…”

Quick Summary
- Use “If I were” for hypothetical, unreal, wished, or imagined situations.
- Use “If I was” for real past events or factual conditions.
- Remember fixed phrases: “If I were you” and “I wish I were” always use “were.”
- Check the verb: The subjunctive only changes the verb “to be” (was → were).
- Test with “he/she/it”: If you would say “were” for he/she/it, use “were” for I.

FAQ
1. Can I ever use “If I was” in a hypothetical sentence?
In very informal or spoken English, some people use “If I was” for hypotheticals. However, for standard written English and formal situations, always use “If I were” for unreal conditions. Stick to the rule for clear, correct grammar.
2. Does the subjunctive mood apply to other verbs besides “to be”?
Yes. The subjunctive also appears with other verbs, especially after words like “suggest,” “recommend,” “demand,” or “insist.” For example: “I suggest that he go now” (not “goes”). The verb does not change for third person singular in the subjunctive.
3. Is “If I were you” always correct?
Yes. “If I were you” is a fixed expression in English. It is always subjunctive because you are imagining being someone else. Never say “If I was you” in standard English.
4. How do I know if a sentence is “real” or “unreal”?
Ask yourself: Is this true or possible right now? If the answer is no (e.g., you are not a bird, you are not the president), it is unreal. If the answer is yes or it happened in the past (e.g., you were late), it is real. This simple test helps you choose “were” or “was.”
