“Was” vs “Were”: What’s the Difference?
Quick Answer:
Use was with:
I
he
she
it
Use were with:
you
we
they
So:
I was tired
they were late
There is one extra twist: in hypothetical situations, English often uses were instead of was, especially in phrases like:
If I were you...
That is why this pair confuses so many learners.
Examples:
Was with singular subjects
✅ She was at the meeting yesterday.
✅ It was a long day.
Here, was matches singular subjects.
Were with plural subjects
✅ They were ready on time.
✅ We were surprised by the result.
Here, were matches plural subjects.
The special case: “you”
✅ You were very helpful.
Even when you refers to one person, English still uses were, not was.
Hypothetical or unreal situation
✅ If I were you, I’d wait.
This is one of the most important non-literal uses of were. The speaker is not saying “I was you” in the past. The speaker is imagining an unreal situation.
Common contrast
❌ If I was you, I’d wait.
✅ If I were you, I’d wait.
In everyday speech, some people do say if I was you, but if I were you is the standard form learners should know.
Common Mistake:
The most common mistake is assuming the choice is always about singular vs plural.
That is only part of the rule.
Yes:
he was
they were
But English also uses were in imagined, hypothetical, or unreal situations:
If she were here...
I wish it were easier.
Another common mistake is forgetting that you always takes were in standard English:
❌ You was late.
✅ You were late.
Quick Tip:
Use this quick rule:
was = singular past reality
were = plural past reality, and many hypothetical situations
A simple memory trick:
I was / she was / it was
you were / we were / they were
If I were... = imaginary
If the sentence is about a real past fact, ask:
Who is the subject?
If the sentence is about imagination, advice, or something unreal, were is often the better choice.
