Most of the times, people use the negative past tense wrongly
Confused about the correct usage of negative past tense? Learn through this thread its correct usage.
People usually use double past tense in a sentence. The helping verb describes the tense in which the action is done and hence we can use the root verb instead using the past tense of the verb. For example,
We didn't take it.
Here, "did not" is the helping verb which shows the action is done is the past tense. Hence we need not say the main verb in past tense. Usually I notice people use it wrongly. Example
We didn't took.
We do not have to use the past tense of the main verb as the helping verb already describes the tense of the verb. People usually make mistake while speaking the negative past tense.
