Determiners and quantifiers

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 would like to ask which of the following is correct
1. I will call you tomorrow at 10?OR
2. I will call you tomorrow at 10 am?
Thank you in advance

Hello agie

Both are grammatically correct. If it's clear that you're talking about the morning, then 1 is probably sufficiently clear.

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

A comma shouldn't be used after passenger because "Andy" is specifying who the passenger is; it's a subordinating clause.

NB Apologies, I misread the sentence of your first example, "When Kim's passenger Andy finds something" Andy needs to be enclosed in commas because it's a parenthesis in apposition (identifies or gives more information about the noun that preceds it). Correct punctuation - "When Kim's passenger, Andy,"
Your second example, "Mark Miles and his son Andy are" doesn't need amended - a comma isn't required because "and" is acting as a coordinating conjunction connecting two nouns (Mark and Andy).

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.

The two examples you gave both have the wrong grammatical aspect; they are written in present progressive of the verb 'to invite' (with the added error "to" & "of" preceding it.)

"It's a pleasure to invite you all for today's dinner." - This is the present simple aspect

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.
