Pronouns are words that take the place of nouns. We often use them to avoid repeating the nouns that they refer to. Pronouns have different forms for the different ways we use them.

I think 'had' is the correct option. The sentence is in the reported speech, with a past tense reporting verb, 'said'. As such the reported part too should have a past tense verb.

A Student belongs to a university distinguish me about IT & Software Engineering like that way; " IT guys does the developing work while the
Software Engineers does the programming job"
I could make sense with it why did she use " while" in this sentence.

Hello Imran,

In this sentence, 'while' means 'but', which is one of several meanings of this word (if you follow the link, you'll see the definition and examples for this meaning, but if you move up and down the page you will see the others). Please note that in this sentence, the verb should be 'do' instead of 'does', since 'IT guys' and 'software sngineers' are plural subjects.

In school time I have read different kinds of noun like,abstract noun,materials noun & other. but I haven't found such kind of noun here.

Hi Imran,

Our grammar covers what its author (Dave Willis) thought were the most essential points learners need to become proficient speakers. It is not a comprehensive grammar -- a complete grammar of English would be very large and would not really fulfil the purpose of our site.

The Wikipedia and Cambridge Dictionary websites are good places to begin checking some topics such as the ones you mention. For example, the Wikipedia Noun page has a section on abstract and concrete nouns and the Cambridge Dictionary page on Nouns also explains this to some degree.

If you have any specific questions about a particular point, please let us know.

All the best,

Hello Sir,
I have no concept how to appropriate use of "while" & "during".
Please let me sense of it.

Hello Imran26,

The meanings of 'while' and 'during' are very similar. Both describe the time within an ongoing activity or state. The difference is that each is followed by a different form.

After 'while' we need a clause with a subject and a verb, or else a present participle (-ing form):

I saw him while I was working.

I saw him while working.


After 'during' we need a noun:

I saw him during the meeting.

thank you Sir Peter.

Thanks a lot. ☺️

In the direct speech, if the statement is: She said, "Our brother has left", what "our" will be changed into in the indirect reporting? Will it be "their brother..." or "her brother...? Please also explain the reason therefor.
