Which is a correct sentence?
I have purchased a computer from you. or
I purchased a computer from your.
I always have this confusion which one is the correct one. I see both form of the sentences. I also hear people saying I have asked him/her or I asked him/her. Which one is the correct English.
Also when can you used "have" in past tense?
I have purchased a new computer (and I am very happy about this).
We use the past tense purchased when we are clearly locating the action in past time:
I purchased a new computer from you last week.
Is your next question about the use of the verb HAVE in the past tense, or the use of this form to construct a past perfect, as in I had purchased?
