Is “I have posted the letter last week” grammatical?












0














Is this sentence grammatically OK? Take a look at this sentence:




I have certainly posted the letter last week. I wonder why it hasn't arrived yet.




So what is the problem with this sentence?

I took a look at the answer sheet. At the first part of the sentence, the modal verb "have" is incorrect. What's your idea?

          Because the present perfect is incompatible with an explicit time reference to a period that is finished.



          If the time period is still continuing, then either the simple past or the present perfect is possible:




          I have certainly posted the letter this week.



          I certainly posted the letter this week.




          (The difference is in how the speaker is choosing to characterise the temporal relationships - the first emphasises that "this week" is continuing, and chooses to see the posting as an event that is relevant to the present. The simple past treats the posting as a finished action, ignoring the fact that it is located in a time period which encompasses the present).



          But with "last week", only the simple past is possible.

            Last week is finished. You need simple past tense: I certainly posted the letter last week.



            Btw. Have isn't a modal verb. It's an auxiliary in the present perfect structure.
