Negatives in Compound Tenses
Many English tenses are compound tenses, meaning their verb phrases contain one or more auxiliary verbs helping a main verb (e.g., is running, has eaten, will be working, should have been sleeping).
There is one universal and strict rule for making compound tenses negative:
The First Auxiliary Rule: Place the negative particle not immediately after the first auxiliary verb in the verb phrase.
1. Tenses with One Auxiliary Verb
In tenses like the Continuous (Progressive) and Simple Future, there is only one auxiliary verb helping the main verb.
A. Continuous Tenses (am/is/are/was/were + Verb-ing)
Place not after the form of to be:
- Positive: She is reading a book.
Negative: She is not reading a book.
Contracted: She isn’t reading. - Positive: We were driving fast.
Negative: We were not driving fast.
Contracted: We weren’t driving.
B. Simple Future (will + Verb 1)
Place not after will:
- Positive: They will arrive tomorrow.
Negative: They will not arrive tomorrow.
Contracted: They won’t arrive.
C. Perfect Tenses (have/has/had + Verb 3)
Place not after the form of have:
- Positive: I have finished my task.
Negative: I have not finished my task.
Contracted: I haven’t finished.
2. Tenses with Multiple Auxiliary Verbs
In perfect continuous or future continuous tenses, we have two or three helping verbs (e.g., will be, has been, will have been). The rule remains the same: place not after the first auxiliary only.
A. Perfect Continuous Tenses (have/has/had + been + Verb-ing)
Place not after have/has/had (first auxiliary), not after been:
- Positive: He has been sleeping all afternoon.
- Negative: He has not been sleeping all afternoon.
- Contracted: He hasn’t been sleeping.
- Incorrect: He has been not sleeping.
B. Future Continuous Tense (will + be + Verb-ing)
Place not after will, not after be:
- Positive: We will be traveling next week.
- Negative: We will not be traveling next week.
- Contracted: We won’t be traveling.
- Incorrect: We will be not traveling.
C. Future Perfect Continuous (will + have + been + Verb-ing)
Place not after will (first auxiliary):
- Positive: I will have been working here for 10 years.
- Negative: I will not have been working here for 10 years.
- Contracted: I won’t have been working.
- Incorrect: I will have not been working.
