Expert writing Tips
Best practice
Always use the base form of the verb after "did not" or "didn't". For example, use "I didn't add" instead of "I didn't added".
Common error
Avoid adding the -ed ending to the verb when using "did not". The "did" already indicates the past tense, so the main verb should remain in its base form. A common mistake is to say "I didn't added", but the correct form is "I didn't add".

FAQs
What is the correct way to say "I didn't added"?
The correct phrasing is "I didn't add". The auxiliary verb "did" already indicates the past tense, so the main verb "add" should be in its base form.
Are there other ways to express the idea of not including something?
Yes, you can use phrases such as "I didn't include", "I left out", or "I omitted" to convey a similar meaning.
Why is "I didn't added" grammatically incorrect?
The phrase is incorrect because "did" is the past tense form of "do" and it requires the base form of the verb. Using "added" after "didn't" is redundant and violates standard English grammar rules.
Can I use "I hadn't added" instead of "I didn't add"?
While "I hadn't added" is grammatically correct, it implies a different tense and meaning. "I hadn't added" uses the past perfect tense, suggesting something wasn't added before a specific point in the past, whereas "I didn't add" simply states that something wasn't added.
