Richard Bollard - 13 Jan 2009 02:11 GMT
I thought this one was simple but the more I look at it, the more
unsure I become.

"There is an endless number of prime factor graphs that have the same
underlying graph."

I would re-write it as "An endless number ..." but that is not
permitted this time.

Should it be "There is" or "there are"?

Is rewriting it as "There are infinitely many..." permitted?

> Should it be "There is" or "there are"?

You can make a case for either.  I'd write "There are", since I'd
write "An endless number of prime-factor graphs have..."

My opinion only, of course: Both are okay.  Use the one that sounds
better to you. I slightly prefer "are."

I would use "there are" because in terms of meaning, the subject is
plural "graphs" and the "endless number" just a way of saying how many
there are. Consider "An endless number of prime factor graphs are
derived from the same underlying graph" - that would sound wrong with
"is".

That's also what I think. Writing "is" is a consequence of imposing a
logic on the language that it doesn't have.

Why use the unprofessional sounding 'endless number'?
No mathematician would put it that way.
It is suitable for popularizations, or undergraduate text,
and that clashes with what follows.

Obvious substitute: 'are infinitely many prime...'

Conventional parsing answers your question unambiguously.
1.  Identify the main verb . . . IS
2.  Identify its subject . . .  NUMBER
3.  Rule = Verbs must agree in number with their subjects
4.  Assessment:  the verb and subject are both singular i.e.
agree in number, therefore the grammar is correct.

We can now see syntactical problems.
A.  This is an "existential statement" of the type THERE IS/ARE
ABC SUCH THAT XYZ.  This is usually wordy and unnecessary,
i.e. we can often write ALL ABC DO XYZ or something similar.

B.  "Endless number" is suspicious.   Several adjectives correctly
describe numbers (e.g. odd, cardinal, prime) but some others
do not (e.g. green, lefthanded.).  A series can be "endless" but
we do not say numbers are endless.  We may say a number
is very large, or infinite, or something similar.

C.  Graphs are constructs representing data.  It seems
irregular to say some graphs "have" other graphs.

It looks as if you were trying to say very many prime factor
graphs display the same shape -- but we are still uncertain
whether you mean they display the same character as each
other or the same as a single "underlying" graph mentioned
earlier.

It looks as if you need to rethink what you want to write.
Your instincts seem OK because your first draft (above)
is grammatically correct.

There is an...

You cannot say "There are an..."

There are an awful lot of ways to refute that. I get 20 million hits
on Google for "there are an".

To me, "a number of" is no more singular than "a hundred".  Well, not
much more.

Quite true, but Richard said he wasn't permitted to.

I'm inclined to agree.

I suspect he's talking about the graphs of graph theory, not those
that display data.  See
http://en.wikipedia.org/wiki/Graph_theory and links therein, if you're
interested.

One of my harder courses in graduate school (MSCS). I hadn't done a
formal proof in over 15 years when I took that.

When the subject is singular, use a singular form of the verb.

"A small number of men was there".

Thanks all. I have passed the comments on to those who asked me. I am

>>"A small number of men was there".

I'm not sure it's quite that straightforward. What agrees with the verb is
the head of the noun phrase that forms the subject, and while in "the number
of elephants is increasing" the head is clearly "number", if the subject is
"a number of elephants", on the other hand, while the grammatical head is
still technically "number" the semantic head is "elephants", with "a number
of" functioning as a kind of determiner, like "some".  For this reason I
would be much more likely to say "the number of elephants in the garden is
increasing" but "a number of elephants are in the garden" or "a small number
of men were there".

This argument seems to be that semantic doctrine permits
overriding the rules of grammar.   If so, it seems an obsolete argument.

We proceed ultimately from usage.  Our rules of grammar are
patterns repeated so nearly universally (and without exception)
that we certify those patterns as "rules" as if a priori, even while
we admit they are generalizations from use (a posteriori.)   There
seems no basis for an equivalent set of syntactic rules.   Even
if there were such a set, our accepted foundation for it would
not permit symantic rules to override rules of grammar.

We do not need such a meta-rule.   Some common speech does
indeed contravene prior rules of grammar, hinting that those
rules may change in future.
