Meet today's English in a real situation — no rules yet. Read it once and try to guess the pattern in the words in bold. Underlined words open a short definition.

Tom and Anna are talking about yesterday.

Tom: Hi Anna. I called you yesterday afternoon, but you weren’t at home. Where were you?

Anna: Oh, hi Tom. I was at the dentist. I was there for two hours!

Tom: Oh, dear. Was it painful?

Anna: No, it wasn’t too bad, but I was very nervous. What about you? Were you at work?

Tom: No, I wasn’t. Yesterday was my day off. In the morning, I was at the park with my dog. The weather was beautiful.

Anna: That’s nice. Were your parents with you?

Tom: No, they weren’t. They were at the supermarket. They were very busy all day.

infoNOTE
Notice how we use was for singular subjects (I, yesterday, it) and were for plural subjects (you, they, parents).

Now the rules behind what you just saw — explained simply, with examples. Underlined words open a short definition — hover on desktop, tap on a phone.

Just as am, is, are are the present forms of the verb to be, was and were are the past forms. We use them to talk about finished states, emotions, locations, and identities in the past (e.g., yesterday, last week, in 2010).

Present vs. Past

Here is how the verb “to be” changes from present to past:

Pronoun Present Past Example
I am was I was at home yesterday.
He / She / It is was It was cold last night.
We / You / They are were We were in class this morning.
infoNOTE
Notice that I, he, she, and it all use was. We, you, and they all use were.

Positive and Negative Forms

To make negative sentences in the past, add not after the verb. In everyday conversations, we almost always use the contracted forms: wasn’t and weren’t.

Subject Positive Negative Contraction
I / He / She / It was was not wasn’t
We / You / They were were not weren’t
format_quoteEXAMPLE

“Yesterday, she was sick, so she wasn’t at work. She was at home in bed.” “We were happy to see them, but they weren’t very friendly.”

Questions and Short Answers

To ask questions, put Was or Were at the beginning of the sentence (before the subject). Do not use the helper verb did!

Structure: Was / Were + Subject + Complement?

  • Were you at home last night? → Yes, I was. / No, I wasn’t.
  • Was the exam difficult? → Yes, it was. / No, it wasn’t.
  • Where were you yesterday? → I was at the beach.
  • Why was he late? → Because he was tired.
warningWARNING
Never use did to make questions or negatives with was or were! Incorrect: Did you were at home? / I didn’t was at work. · Correct: Were you at home? / I wasn’t at work.

Common Time Expressions

When talking about the past, we often use words that show when the action happened:

  • Yesterday (yesterday morning, yesterday afternoon)
  • Last (last night, last week, last month, last year, last Sunday)
  • Ago (ten minutes ago, two days ago, a year ago)
warningWARNING
In English, we say last night, NOT yesterday night.

Common Mistakes for Spanish Speakers

  • Using singular ‘was’ with plural pronouns: Incorrect: We was late for the party. Correct: We were late for the party.
  • Using ‘did’ / ‘didn’t’ to form past questions/negatives for ‘to be’: Incorrect: Did she was happy? / I didn’t was tired. Correct: Was she happy? / I wasn’t tired.
  • Translating “yesterday night” directly from Spanish “ayer por la noche”: Incorrect: I was at home yesterday night. Correct: I was at home last night.
boltQUICK REVIEW
  • Singular: I / he / she / itwas / wasn’t
  • Plural/You: we / you / theywere / weren’t
  • Questions: Put the verb first — Were you tired? (Never use did)
  • Key terms: yesterday, last night (not yesterday night), ago
