Hello. Could you please help me?
Which pronoun is correct?
- One's parents know what is best for (one - him).
Thank you.

Hi Ahmed Imam,

One is the best answer here. Him is grammatically correct, but only suitable if the speaker is referring to a person who is male, e.g., talking about how to raise a son (specifically a son, rather than a daughter). One is not limited to only male persons.

But using one is typical of a very formal style. A more common way to say this would be (Your) parents know what is best for you.

I hope that helps.

Hello can you please tell me what is the correct form of loaf and shelf as plural noun
Loafs ,shelfs/ loaves,shelves
And why

In English If a word ends with F, in plural you change it to V. Like thief > thieves.

Hello Raf,

That is true for some words, but there are many words that end in 'f' that have a regular plural ending. For example: 'roof' ('roofs'), 'belief' ('beliefs') and 'chef' ('chefs').

It's a good idea to check the spelling in a dictionary when you have any doubt.

All the best,

hi! Is it grammatically correct to say "The job of the government accountants intrigued me the most as they are said to be THE ONES who manage and monitor public funds, maintain fiscal transparency, and combat white-collar crimes and other fraudulent activities."

Hello shnx,

Yes, 'the ones' is used correctly in this sentence. I'd suggest putting a comma after 'the most' and before 'as' -- when 'as' means 'because', we generally put a comma before it.

All the best,

Hello, I got confused with this sentence.

Those four volcanoes are one of the most active.

Hello Melvin1234,

I'm not surprised you got confused. The sentence is not grammatical.

You could say this:

Those four volcanoes are some of the most active (in the region/in the world etc)
