I have run the program. vs I have ran the program.

[Nbvinay]

Hi Alan / All,

Could you please tell me which sentence is correct? And why it is correct?

1) I have run the program.
2) I have ran the program.

In computer it’s showing 1st one is correct.

Thanks in advance

[Milanya]

Your computer is correct.
"I have run the program." or " I ran the program yesterday."

"I have run the program" is Present Perfect.

To make the present perfect,we use: have/has + past participle.
Run is an irregular verb.
The past participle of "run" is "run."

Hi Milanya, How do you remember all these things? For me it's very difficult to remember. Now I understood this, after one week I will forget this concept? How to remember all the grammar exists in English as I am non native speaker of English.

Please give me some suggestions

Thanks in advance.

Hi Milanya, How do you remember all these things? - I practice a lot. I live in an English speaking contry, which also helps.
For me it's very difficult to remember. Now I understood this, after one week I will forget this concept? How to remember all the grammar exists in English as I am non native speaker of English.

Please give me some suggestions. - Read a lot, study, practice, come to this forum often. Nothing I suggest is very new and anusual. I do not know about any easy ways, just hard work.

You cannot learn things overnight, and it wouldn't be that easy, especially for nonnative speakers like you. Learn the rules of English by heart and persevere.

Hi Vinay,

It seems that you are still not feeling comfortable with the grammar yet.
Frankly speaking, grammar is not easy, I do not fully master it either.
In your case, however, it is not very difficult to determine which one is the correct sentence.
Milanya already explained to you very clearly.
If you don’t mind, I would like to share with you a more detailed but boring explanation as follows so you can memorize the rules more easily.

( 1 ) Simple Present, ( 2 ) Simple Past, ( 3 ) Past Participle

( 1 ) ( 2 ) ( 3 )
come came come
see saw seen
do did done
run ran run
work worked worked
. . . . . . . . .

In simple present tense, simply use the verb in column one as the main verb. Never use “have”, “has” or “had” before the main verbs.
e.g. I do, you do, he does, it does, she does, they do, we do etc. ( correct )
For singular subjects such as he, she and it, we use the singular verb “does” instead of “do”.
Counter examples : I have do, you have do, he has do, … ( incorrect )

In simple past tense, simply use the verb in column two as the main verb. Again, never use “have”, “has” or “had” before the main verb.
e.g. I did, you did, he did, it did, she did, they did, we did etc. ( correct )
There is no difference between single verb or plural verb.
Counter examples : I have did, you have did, he has did, I have ran, you have ran, he has ran, … ( incorrect )

In perfect tense, we use the main verb in column three ( Past Participle ) as the main verb no matter it is a present perfect or a past perfect tense. In addition, we need to add a verb ( have, has or had ) in front of it as an auxiliary verb.
In present perfect tense, e.g. I have done, you have done, he has done, it has done, she has done, they have done, we have done etc.
Once again, for singular subjects he, she and it, we use “has” instead of “ have ”.

In past perfect tense, we add the verb “ had ” before the main verb in column three as an auxiliary verb.
e.g. I had done, you had done, he had done, it had done, she had done, they had done, we had done etc.

In your case, the first sentence “ I have run the program ” is a present perfect tense.
The sentence is grammatically correct since it consists of the auxiliary verb “have” and also followed by the main verb “run” in the column three ( past participle ). However, you must not be confused with the “run” in column three and the “run” in column one although they have the same spelling. We MUST use the verb in column three and NOT in column one nor column two.

As a simple rule, whenever the auxiliary verbs “have”, “has”, or “had” is used, the main verb directly following it MUST be a past participle in column three.

In your second sentence “ I have ran the program ”, needless to say, is incorrect because the verb “have” may not be followed by a verb in column two.

Hope this help, and not boring too.

P.S. I wanted to make a table for the three columns of the samples of verbs like in the EXCEL or a table in WORDS but failed. I have tried to copy from WORDS or EXCEL but the grids disappeared after copying and all the words in each column misaligned. I can’t use the TAB key in the keyboard for alignment purpose. Could anyone tell me how to create a table in our text in this forum ? Many thanks.

Hi Nick,

Thank you very much for your detailed explanations and your valuable time.

It’s not at all boring .It helped a lot to me to improve my weaknesses in the tense and past participle forms. From your explanations I come to know that I have to master basic things like past participle forms first, and then only I can easily understand tense clearly.
You spent your valuable time to explain this concept by giving example and by making table and all, I am very thankful to you.

I really appreciate your help.

Many Thanks
Vinay

**** Please correct me if I made any grammatical mistake in this post, so that I can improve it. *******

In Chinese, we always use “ Although . . . . . . . . , but . . . . . . . ” to emphasize the contrast.
In English, we don’t use the “ although” and “but” in the same sentence because they are considered to be redundant.
