subject verb agreement

[svartnik]

A large number of sudents have failed the exam.

IF I am not mistaken, have should be has.

Which is the subject in this sentence?

It is number

The parts highlighted in read are the subject modifiers.
The first verb of the finite verb phrase is have.
My grammar book says the subject-verb agreement means the subject has a relationship of concord with the verb.
The subject (number) is 3rd person singular, and the verb form is not (have)

Why is this construction still regarded standard?

Cambridge Dictionaries Online - Cambridge University Press
A small number of children are educated at home.

I would like to invite comments.
Thanks

Hi Svartnik

A [ large ]number of ... + verb in the plural

e.g. A number of workers are on strike. [ Subject- workers]- students - in your sentence

a number of- a determiner

The number of...+ verb in the singular

The number of students is ....[ Subject- number]

Although the expression 'a number' is strictly singular, the phrase 'a number of' is used with plural nouns (as what grammarians call a determiner). The verb should therefore be plural: 'A number of people are waiting for the bus'.

Thus :

The expression "the number" is singular
e.g.The number of failures is decreasing

The expression "a number" is plural
e. g. A number of people are leaving

Hi

Oh, then ,neither 1 nor 2 is correct. I should have thought that "myk" comes from Mike .

Thank you

hello,
"A [ large ]number of ... + verb in the plural" -- this is not true
"A small number of children are educated at home."
"SLIGHTLY FORMAL A large number of invitations has been sent"
Cambridge Dictionaries Online - Cambridge University Press
MY take:
A large(modifier) number (Subject) of people (post modifier) is (verb) leaving -- number, is -- grammatical concord
number, are -- notional concord (a large number of = many)

Hi Svartnik

I`m sorry but I have to contradict you.
As I have already explained "a number of" is a determiner and the SUBJECT is
"workers" [ NOT NUMBER !!]in the sentence : A large number of workers are on strike. [workers are on strike not number!!].
Large is indeed an adjective which does not have any influence on the subject-verb agreement.
See also Mykwyner`s [ who is a native !]agreement on this problem of English grammar

and some more examples :

Expressions using the phrase "number of" depend on the meaning of the phrase:
They take a singular verb when referring to a single quantity:
The number of students registered in the class is 20.
They take plural verbs when they are used as indefinite quantifiers :
A number of students were late.
Expressions of Quantity

Subjects preceded by the number of or the percentage of are singular, while subjects preceded by a number of or a percentage of are plural.
 Example: The number of vacationers in Florida is increasing.
 Example: A number of vacationers are young people. However, a large percentage of the vacationers are senior citizens.

Hi

Being a native and being a grammarian are two things, IMO.
Do not take me wrong, I am not saying Mike is not the best grammarian in the world.
What is news to me is that the subject of the sentence is the object a preposition (of)

"SLIGHTLY FORMAL A large number of invitations has been sent."
Why is the verb in singular here, then?
