Determiners and quantifiers are words we use in front of nouns. We use determiners to identify things (this book, my sister) and we use quantifiers to say how much or how many (a few people, a lot of problems).

Read clear grammar explanations and example sentences to help you understand how determiners and quantifiers are used. Then, put your grammar knowledge into practice by doing the exercises.

I'd like to ask you about that, is that really a comma can be omitted in these case which are showed below?
"When Kim's passenger Andy finds something . . ." IS NEEDED a COMMA after PASSENGER i.e. it should be looked like "When Kim's passenger, Andy finds something . . ."
2 "Mark Miles and his son Andy are . . ." I think it is correct according the source above
Please check it
thank you

Hello Vitub

I'm afraid I don't know enough about either sentence to be able to know what they mean, so I can't really explain them or offer any other recommendations about them. If you include the full sentence, we might be able to help you more, but please note that in general we don't explain sentences that come from other texts unless you have a very specific question about them.

All the best

Hi, Please advise which is the most appropriate usage & explain the reason.

1. It is my pleasure to inviting you all for today's dinner.
2. it is my pleasure of inviting you all for today's dinner.

Hello Sooraj

The form I would recommend here is 'to invite all of you'; the other two options are not correct in standard British English.

e.g. - she is the same girl who sang beautifully at the concert yesterday.
OR she is the same girl that sang beautifully at the concert yesterday.

which one is correct? I've heard after all, same, everyone,etc. "that" is used.

Hello tshantanu0,

The structure here is a defining relative clause and you can use either 'who' or 'that' as the relative pronoun here - it makes no difference. I'm not aware of any rule which says 'that' needs to be used after those words.

You can read more about relative clauses on these pages:

Can the Partitive Nouns or Group Nouns followed by 'of' be used as Determiners?

Hello Atuar Rahman,
I think it will be easier to answer your question if you provide concrete examples of what you have in mind. Please provide some and we'll be happy to answer.

Dear sirs,

This is the first sentence of a paragraph on writing tips: "It’s important to keep one person per dialogue so you do not confuse the reader."

Why does this sentence use "the reader?" Could I say readers or the readers in the place of the reader? How does the meaning of the sentence change?

I struggle to identify whether "the reader" is a definite or indefinite noun.

On the one hand, it appears a definite noun since the reader means your reader; in this case, isn't a plural form ("the readers") more appropriate? On the other hand, it appears as readers in general. In this case, should not we use simply readers, not "the reader" as the sentence does.

Many thanks.

Hello cbenglish,
The definite article is used here because the speaker is referring to a particular, if imagined, reader:
> the reader who is reading your text <

Other forms are also possible, depending on how the speaker imagines the situation:
> ...the reader (a person who is reading your text)
> ...the readers (a group of people who are reading your text)
> ...readers (any people who may read your text)
