Didn’t go, not didn’t went: past negatives
You planned a museum visit yesterday, but the building was closed. Explain what you and your friend did not do.
Professor Scott MendozaThe short answer
For ordinary past actions, use did not or didn’t followed by the base verb: I didn’t go. Did carries the past marking, so went returns to go and bought returns to buy. The pattern is the same with I, she or they.
After didn’t, return to the base verb.
A positive past sentence can use went or bought. To make these actions negative, add didn’t and use go or buy instead. The base verb is the dictionary form, without -ed, -s or to.
One visit, positive and negative
I went to the museum.
I didn’t go to the museum.
She didn’t buy a ticket.
She didn’t buy uses the same didn’t as I didn’t go. Do not change it to doesn’t for a past action.

Yesterday, I ___ inside. Choose the past negative of go.
didn’t goDidn’t marks the past; go stays in its base form. Didn’t went repeats past marking on the main verb.
Mia bought no ticket yesterday. Which sentence uses the past negative correctly?
She didn’t buy a ticket.Use didn’t buy, not didn’t bought. Does not belongs to the present pattern and still needs a base verb.
The film was available yesterday, but your friends chose not to watch. Complete: “___”
They didn’t watch it.They didn’t watch it describes the past decision. After didn’t, watch has no -ed.
Put it into practice
Repair the museum update.
Keep both actions negative and in the past. Correct both main verbs.
I didn’t went inside, and Mia didn’t bought a ticket.
See a model answer
I didn’t go inside, and Mia didn’t buy a ticket.
The auxiliary did carries the past tense in each negative, leaving go and buy in the base form.
A little more clarity
Common questions
A few useful details before you move on.
Is did not also correct?
Yes. Did not and didn’t express the same basic negative. The full form can add emphasis; both take the base verb.
I did not buy a ticket.
What about was and were?
Add not directly to was or were: wasn’t or weren’t. Do not apply didn’t + base verb to past be in these simple sentences.
The museum wasn’t open.
Take it into your day
Use didn’t + base verb: didn’t go, didn’t buy, didn’t watch.
