i'm again here with a new problem!!!

[asad hussain]

Which one of following sentences sounds more polite. And do I need to put “the” before “school”?
Your child is unable to write. Kindly pay a visit to school.
Your child is unable to write. Kindly call in on school.

I like:

Your child is unable to write. Please call or visit the school.

There are other equally correct and polite ways to say this.

[asad hussain]

Aren't the sentences written above grammatically correct? Some one told me that the first one sounds informal while the other formal. And why have you added "the" before "school". Could you please explain it to me. I'll so thankful to you.

[asad hussain]

Can't I say "Please pay a visit to the school."?

[mykwyner]

We use the article the for clarity, so the reader knows which school you mean. Call in on... is not good idiomatic English. Also, please is more widely used than kindly.

Gramatically correct sentences can contain non-standard or unclear usages.

[asad hussain]

thanks a lot for the deal of help, mykwyner!!!
Can't I say "pay a visit" instead of "visit"?

[Tdol]

Yes, you can.

[asad hussain]

Thanks Tdol!!! I am really thankful to you for dropping in on the post and helping me clear the mass of confusion.

You're welcome, Asad.
