▷ Present Perfect tense negative sentences

The present perfect tense is used for describing actions or events that either occurred at an unknown time in the past, began in the past and continue into present day, or both. To form this tense, an auxiliary verb (“have” or “has” for third-person singular subjects) is followed by the past participle of the main verb.

Utilization of Present Perfect Negative Sentences

Present perfect negative sentences are used to indicate that an action or event has not taken place up until now. They consist of an auxiliary verb “have” or “has”, the past participle of the main verb, followed by the negative particle “not” (often contracted to “n’t”).

Negative sentences with “not” after an auxiliary verb “have” or “has,” indicate that the action or event being described has not taken place prior to now. For instance, “I haven’t finished my homework yet” implies the speaker has not completed their assignment up until this present moment.

The present perfect tense is often employed to describe experiences, actions or events that began in the past and continue up to present day. It also serves to describe completed actions or events with a current relevance. When forming negative sentences, remember to include “not” after any auxiliary verb like “have” or “has,” this indicates that an action or event has not taken place up until this present moment.
