Ever found yourself stuck wondering, “Should I say wasn’t or weren’t?” You’re not alone. These two little verbs cause a lot of confusion, even for native English speakers. Let’s clear the fog once and for all.
The Basics: What’s the Difference?

Both “wasn’t” and “weren’t” are contractions of the past tense of “to be.” They mean “was not” and “were not,” respectively.
Contraction | Full Form | Used With |
---|---|---|
Wasn’t | Was not | Singular subjects (I, he, she, it) |
Weren’t | Were not | Plural subjects (we, you, they) & Subjunctive mood |
At a glance, it’s all about subject-verb agreement but as you’ll see, the subjunctive mood throws a curveball.
When your subject is singular like “he,” “she,” “it,” or even “I” . Lou you’ll usually use “wasn’t.” Let’s look at a few cases.
✅ Correct Usage:
- I wasn’t aware of the deadline.
- He wasn’t at the meeting yesterday.
- The movie wasn’t as good as expected.
❌ Incorrect:
- They wasn’t prepared. → (Plural subject, wrong verb)
Use “Weren’t” for Plural Subjects (Past Tense)

When your subject is plural like “we,” “they,” or “you” you’ll want to use “weren’t.”
✅ Correct Usage:
- They weren’t convinced by the presentation.
- You weren’t on the guest list.
- The animals weren’t kept in cages.
❌ Incorrect:
- She weren’t feeling well. → (Singular subject, wrong verb)
Here’s Where It Gets Tricky: The Subjunctive Mood
Ah, the subjunctive mood that rare, often-overlooked cousin of standard verb tenses. It deals with hypothetical or unreal situations, wishes, or counterfactual statements.
And here’s the golden rule:
Use “weren’t” instead of “wasn’t” with singular subjects in the subjunctive.
This includes “I,” “he,” “she,” “it” even though they’re usually paired with “was.”
✅ Examples:
- If I weren’t so tired, I’d go to the gym.
- I wish I weren’t afraid of heights.
- If it weren’t for you, I’d still be stuck.
❌ Incorrect:
- If I wasn’t taller, I couldn’t reach the shelf. (Should be “weren’t”)
Why? Because we’re talking about something unreal or imagined, not a factual statement.
Real-World Example: Email Scenario
Let’s say Emma is writing to her boss after missing a team call:
Subject: Apologies for Missing the Meeting
Hi Daniel,
I sincerely apologize for missing today’s strategy session. I wasn’t feeling well this morning and didn’t want to risk spreading anything.
If it weren’t for this sudden flu, I would’ve been there on time and fully prepared. I’ve reviewed the meeting notes and will follow up with Sam for action items.
Best regards,
Emma
Notice the switch between “wasn’t” (fact: she felt sick) and “weren’t” (hypothetical: if she had been well). This is classic subjunctive mood usage.
Common Mistakes to Avoid
Even advanced learners sometimes slip up. Let’s tackle a few incorrect verb usage examples and fix them:
Incorrect | Why It’s Wrong | Correct |
---|---|---|
If he wasn’t so lazy… | Subjunctive with singular subject | If he weren’t so lazy… |
They wasn’t ready yet. | Plural subject mismatch | They weren’t ready yet. |
The cat weren’t hungry. | “Cat” is singular | The cat wasn’t hungry. |
Quick Test: Can You Spot the Error?
Choose the correct sentence:
- If she wasn’t late, we’d already be there.
- If she weren’t late, we’d already be there.
✅ Answer: Sentence 2. “If she weren’t…” is correct because it’s a counterfactual she is late, so we’re imagining the opposite.
Memorable Trick to Remember

Use “wasn’t” when something actually didn’t happen (factual), and
Use “weren’t” when imagining a what-if world (hypothetical).
You might even say:
“If this article weren’t so helpful, you wouldn’t be reading it right now!” 😉
Key Phrases in Context
To deepen understanding, here’s how some commonly searched phrases fit into real-world usage:
- “Wasn’t it obvious?” Used for rhetorical emphasis with a singular subject.
- “Weren’t it for her quick thinking…” This is actually incorrect. It should be “If it weren’t for her quick thinking…”
- “I wasn’t aware…” Clear past fact.
- “They weren’t convinced…” Plural subject, factual.
- “If it weren’t for…” Hypothetical construction.
- “I wish I weren’t…” Counterfactual wish.
When Both Could Technically Work (But Don’t Mean the Same Thing)
Take this example:
- “If I wasn’t rude, I apologize.” → Here, you’re unsure if you were rude.
- “If I weren’t rude, I wouldn’t have said that.” → This implies you were rude and you’re reflecting on it hypothetically.
Subtle? Yes. But powerful. This shows how context and tone shape verb conjugation choices.
