This post is in response to Piscean's post #48
1A. In existential there + be sentences, the number (singular or plural) of the verb shows that the notional subject is the NP that follows it:
1. There is a book on the table.
2. There are some books on the table.
1B. When the subject of an verb is [NP] and [NP], that subject takes the same verb form as a plural noun does:
3. John is in the garden.
4. Mary is in the garden.
3. John and Mary are in the garden.
5. A computer is essential these days.
6. A mobile phone is essential these days.
7. A computer and a mobile phone are essential these days
Obviously yes to all of the above.
1A + 1B.It therefore seems reasonable to accept [8] below as natural and correct:
8. There are a computer and a TV in my room.
I take issue with the reasoning here. I understand Phaedrus' grammatical argument about derivation, but I'm not sure I agree that that's the best way of thinking about this. My feeling is that the rule of proximity has some bearing on the speaker's selection, regardless of grammar rules, perhaps related to the rule of phonological economy (it being easier to pronounce
there's than
there are) as well as the way that the propositional content is packaged in the mind. I don't have anything more interesting to say about this just yet—I find it quite mysterious.
2A: jutfrank (post 21) says I'd analyse the logic of the sentence as a conjunction of two propositions:
P1: There is a computer
conj.: and
P2: [there is] a TV.
However, in a response to my quoting two sentences from M-W,
there is a lake and several small streams
there are a dog and a few cats in the house,
he does not state that he finds the second unacceptable.
I don't want to say anything about what I find acceptable because the idea of what counts as acceptable deserves a long discussion in itself. Suffice to say that I think there are rules of use in conflict with rules of logic, if you like. I don't strongly disagree with the logic of using
are (in the sentence we've been discussing), but I do count it as unnatural.
As far as logic is concerned, I think both of the M-W sentences are fine.
If they are acceptable, and M-W suggests they are, then it is hard to see how a 'conjunction of two propositions' would work here:
There is a lake
and
[there is ] several small streams.
I would express the conjunction of propositions like this:
There is a lake
and
[there are] several small streams
The verb
are is not pronounced.
I don't see a conjunction of two propositions as possible in
9. There is a computer on the desk and [there is] a TV on the shelf.
any more than I see one as possible in
10. A computer [is] and a mobile phone is essential these days.
There are two propositions going on here. The propositional content can be shown like this:
P1:
A computer is essential these days
P2:
A mobile phone is essential these days
(I might have misunderstood what you meant here.)
I have neither the time to the energy to research this in depth, but a brief look through several grammars and style guides has failed to unearth any helpfully definitive advice.
It seems that some people find only one of the following sentences acceptable, some to, and some all three:
a. There is a computer and a mobile phone on the table.
b. There's a computer and a mobile phone on the table.
c. There are a computer and a mobile phone on the table.
My purely personal view is that I do not like [a], though accept that many people use it. I use [c] and illogically, I admit, also . When I was an IELTS examiner, I would not have penalised a candidate who used any of them.
Okay. Thanks for the energy you have spent—it has been useful and interesting to me, at least. I find this discussion very illuminating. As I've hinted, I find c. quite a lot worse than a. As an IELTS examiner, I wouldn't penalise any of them either.
I would love to be able to do further study on native speakers' thoughts on these three variations.
