Is Coldplay singular or plural?

A good example of the variation permitted between singular and plural for semantically plural but grammatically singular entities like bands in (British) English:


Here we have 'offends' with the singular agreement, and in the very same sentence the plural verb 'are' (contracted to 're).

We also have a pronoun 'they' which can be used for both singular and plural referents, at least in colloquial usage and probably in many formal registers too. However, it's prescriptively plural, and this can affect its usage in funny ways. For instance, it's unusual to hear 'themself' and spellcheckers don't allow it, even when referring to a singular antecedent in a sentence like 'a student has left their file here. They'll be kicking themselves later'.

It's impossible (for me, at least) to refer to a band as 'it'. This is a bit surprising seeing as a band can be singular, as noted above. I don't know the reason for this. But it means that we have to use 'they' and we have a singular verb 'offends' in the tweet above, followed by the frequently singular 'they', followed by the plural 'are', all of which should be one or the other. But because at no point is there a mismatch between two adjacent items, the long distance mismatch comes out just about ok. 'They' mediates between the singular and plural verbs and both are deceived into thinking they're in the right number form.

Lost 'lost ''lost' sign' sign' sign

A wonderful example of centre embedding from a ridiculously silly blog, via my friend Valdemar:

The image shows a lost sign, and the lost thing that it's advertising is another lost sign. And the thing that sign was advertising (before it got lost) was a lost sign... and so on. 


It's called centre embedding because, unsurprisingly, it means embedding a phrase in the centre of another one. By 'in the centre' we don't mean that it's precisely central, but rather that words from the higher-up phrase are on both sides of the embedded one. Here's an example of the more common type of embedding we find in English:

I really hate people [who don't think of others]

The bracketed part is a relative clause, which means that it tells you more about people, and it's embedded in the main clause. It's at the end, which is nice and easy to understand. We can go on for a surprisingly long time like this:

This is the farmer sowing his cornThat kept the cock that crowed in the mornThat waked the priest all shaven and shornThat married the man all tattered and tornThat kissed the maiden all forlornThat milked the cow with the crumpled hornThat tossed the dog that worried the catThat killed the rat that ate the maltThat lay in the house that Jack built!

Every line in that rhyme is a new embedded clause, but we can keep track of it all and it's not terribly remarkable. We actually do it quite a lot in normal speech. This example, which inspired Language Log's Trent Reznor Prize for Tricky Embedding, contains a whole stack of embedded clauses and other stuff but is completely understandable, and was produced in natural speech in an interview:

"When I look at people that I would like to feel have been a mentor or an inspiring kind of archetype of what I'd love to see my career eventually be mentioned as a footnote for in the same paragraph, it would be, like, Bowie."

The thing with centre embedding is that it is totally grammatical (it does not break any of the rules of English (by which I mean the rules that speakers intuitively know and that cannot be broken, rather than the prescriptive rules that we all break in our everyday speech), but not acceptable (i.e. speakers don't say things like this and if asked, don't think they are good sentences at all). This is very different from most other grammatical puzzles that we (linguists) have, which are far more often of the type 'this is ungrammatical in most dialects but some speakers produce it - why?' or 'this theory predicts this to be ungrammatical but it's not, because it occurs in language X - why?'. 


It's really striking how quickly examples of centre embedding get impossible to parse (work out the grammar of). In the poster, we can of course easily understand the phrase with no embedding at all:

Lost sign

But then even just one layer of embedding, equivalent to I hate people who don't think of others, is a bit hard to work out:

Lost lost sign sign

And then when you get just one more, it's too hard:

Lost lost lost sign sign sign

The quotation marks help a bit here, but not much, and that's obviously no good in spoken language. This example is obviously designed for humour, and some are more or less easy to work out. Wikipedia (yeah, I'm being lazy today - I've got a PhD to write) cites this example of double embedding, attributing it to De Roeck et al (1982):

Isn't it true [that example-sentences [that people [that you know] produce] are more likely to be accepted]?

The double-embedded part that might cause trouble is the that people that you know produce part, but here it's not too difficult, perhaps because we're used to hearing know+verb constructions. But the Wikipedia page also says (summarising Karlsson 2007) that three is the maximum degree of embedding in written language, and even two is vanishingly rare in spoken language. It gives this example of super-tricky centre embedding, where the first one (with one level of embedding, and not centre embedding) is fine, but adding just one centre-embedded clause makes it incredibly difficult to parse:

A man [that a woman loves]

A man [that a woman [that a child knows] loves]

It means a man who is loved by a woman, who in turn is known by a child. But you try working that out while you're in full conversational flow. It's supposed to be basically just that while we're super-good at keeping track of relations and actions, we're really really bad at keeping track of a whole load of subjects without linking them to their predicates (what they did). 


Finally, this completely incomprehensible paragraph from SpecGram: 

An apparently new speech disorder a linguistics department our correspondent 
visited was affected by has appeared. Those affected our correspondent a local grad student called could hardly understand apparently still speak fluently. The cause experts the LSA sent investigate remains elusive. Frighteningly, linguists linguists linguists sent examined are highly contagious. Physicians neurologists psychologists other linguists called for help called for help called for help didn’t help either. The disorder experts reporters SpecGram sent consulted investigated apparently is a case of pathological center embedding.
