Hello SonuKumar,

Both sentences are correct. You can use the plural nouns or the singular for generic meaning here.


To my ear, the plural 'What are the prices of...?' is the better choice here. I don't think the singular form is correct in this construction.



The LearnEnglish Team

what is the price of onion and potato in your area.
what is the price of onions and potatoes in your area.

Are both of these correct ?

when to use the noun word 'price' in singular and when to in plural ?

Could you please explain with an example ?

Hello again SonuKumar,

Yes, both of those are correct and speakers can choose which they use.

As I said, I think the most natural choice is 'What are the prices of...', but people will use other forms as well.

Hello sir or madam,

This is related to short form. Is below sentence correct?

Nothing can make you a wise person but your very own experience.

Extra question: Is comma required before but?

Hello Chekytan,

Please note that this is a question of punctuation, which we don't really cover on LearnEnglish. That said, I wouldn't use a comma before 'but' here.

There might be some style guides out there that would disagree, but I think most would recommend against one here.

All the best,

Hello sir,

In a Matrimonial ad I have seen a caption " be found " .

My doubt is
1. Is that caption " be found " a passive sentence.
2. If it is a passive sentence does it mean "be found by someone or something" is this correct.
3. If it is a passive sentence why there is be instead can't we say " is found or are found" .
4. Can we replace "be found" with " to be found ". Does Adding "to" make any difference in the sentence.

Thanks in advance.

Hello Luke warm,

When you say 'caption', you mean the short text beneath a photo? I'd need to see the advert to be able to say for sure, but it might be an imperative (i.e. a command) -- the imperative form of verbs is the same as the base form (first form).

If it is an imperative, it could be a passive verb form (with the meaning you suggest in 2) or it could be a verb + adjective. 'to be found' is a grammatical verb form, but I don't think it'd make much sense in the context you describe (though of course I haven't seen it and so can't say for sure).

All the best,

While any measure that increases women’s sense of safety and the likelihood of conviction is to be welcomed, it does not solve the underlying problem of men failing to accept women’s bodily autonomy.

What is the meaning and function of "to be welcomed" in the sentence above?

Thanks a lot.

Hi AkiraTa05,

X is to be welcomed means 'X should be welcomed' or 'We should welcome X'. 

This use of to be is for giving instructions or obligations. The speaker is telling other people (or him/herself) what should be done. 

Here are some more examples.

  • You are to submit your report by 5 p.m.
  • It was a wonderful day, never to be forgotten.

This use of to be is quite formal in style.

Best wishes,

Hi teacher, could you explain the use of "be to" in the sentences below?

Thanks in advance.
