Question 1

Do you use the past form after didn't?

Accepted Answer

No — this is a very common mistake. After "didn't," you must use the base form of the verb, not the past form. Say "I didn't go" (correct), not "I didn't went" (wrong). The reason is that "didn't" already shows the past tense, so the main verb does not need to change. Think of "didn't" as carrying the past meaning for the whole sentence. This rule applies to all verbs: "She didn't eat" (not "ate"), "We didn't see" (not "saw"), "They didn't know" (not "knew"). The only exception is the verb "be," which uses "wasn't" or "weren't" instead of "didn't."

Question 2

How do you make negative sentences with "was" and "were"?

Accepted Answer

The verb "be" does not use "didn't" in the past simple. Instead, add "not" directly after "was" or "were": "I was not tired" or "She wasn't happy." The contracted forms "wasn't" and "weren't" are used in everyday speech and informal writing. Use "wasn't" with I, he, she, and it. Use "weren't" with you, we, and they. For example: "It wasn't cold yesterday," "They weren't at the meeting." This is different from all other verbs, which use "didn't" plus the base form. Mixing up these two patterns is a common error at A2 level.

Question 3

What is the difference between "didn't" and "did not"?

Accepted Answer

"Didn't" and "did not" have exactly the same meaning — "didn't" is simply the contracted (shortened) form. In everyday spoken English and informal writing, "didn't" is the normal choice: "I didn't see him." The full form "did not" is used for emphasis or in formal writing: "The company did not respond to the complaint." In exams, both forms are accepted. When speaking, using "did not" instead of "didn't" can sound unnatural unless you are stressing the negative: "I did NOT say that!" In Cambridge and IELTS exams, contractions are acceptable in informal writing tasks but should be avoided in formal essays.
