I am so very confused and suspect I am using
is and
are incorrectly, but I just don't know... The more I think about it, the more confused I become.
When I read other people's uses of is and are, I get confused as they always sound wrong to me. Can anyone explain in very simple terms how to use the correct one?
Example
a) A large range of books
is available
A range of is not the same as, say, A lot of, the latter of which is a quantifier after which you use a singular or plural verb depending upon the noun they are used with:
A lot of people were...
A lot of mineral water was...
b) A large range of books
are available
I would use
b when speaking or writing, as it sound correct to me;
a just doesn't seem to flow when read out loud. It sounds odd to me.
I assume that "a large range of books
is avaiable", is correct because range is singular? So, I could say, "manybooks are available",? Maybe?
a) There
is a huge number of people in the world

b) There
are a huge number of people in the world
A number of is a quantifier, hence you use a plural verb only (since number is never used with singular nouns); the number of is not a quantifier, so you use a singular verb with it (followed by a plural verb only):
The number of people was...
In the above, would
a be correct again? Yet again, to me,
b sounds correct.
The more I think, the more lost I become.
Anyone? Can you explain it simply so I can apply the rule in future?
Many thanks
Zoltar.
