Dangling underwater
« previous post |
Bob Shackleton sent a link to this headline: "After 700 Years Underwater Divers Recovered 80-Ton Blocks from the Long-Lost Lighthouse of Alexandria", ZME Science 7/5/2026. His comment: "That’s a long time for a diver to stay underwater…"
Geoff Pullum discussed examples of this kind many years ago, in "Dangling etiquette" (12/14/2003). His verdict: "It's manners, not grammar".
"Does this fall under the no dangling modifier prescription?", asks Rosanne, in a post on The X-bar. Yes, Rosanne, it does. Like participles, adjectives and also some idomatic preposition phrases, when used as adjuncts, need an understood subject (or, it might be better to say, a target of predication) to be filled in if they are to be understood. The prescriptive tradition says that the subject filled in must be the one obtained from the subject of the matrix clause. Here that would be your guests, which makes a nonsense reading, so the sentence cited would be treated as an error.
But the prescriptivists have a problem. Sentences of this kind, which call for you to fill in the understood subject from somewhere else (here, the subject of is light in the subordinate clause), are so common that when I and several friends have spent some time picking new ones up from print and radio sources, we get them at a rate of as many as one per day. That's in edited sources, where grammatical errors have almost entirely been screened out. This just cannot be syntactic error. It's too frequent.
I definitely think that sentences that make you twist this way and that, hunting for the intended subject, are ill-written and discourteous. But it simply isn't reasonable to say that they are syntactic errors. We follow our syntactic rules so much better than we follow this principle of courtesy. The syntax of English says (for example) that the subject should precede the predicate in a normal declarative: The cat wants to go out rather than *Wants to go out the cat. Ever seen anyone get that wrong? I thought not. People mostly know their syntax. Dangling modifier cases fall down on simple courtesy. It's manners, not grammar, that's what I think.

Even with the mortal divers, could be "After 700 years," or "After 700 years underwater," … semantics are mushy however, so I guess a difference only a syntactician would care much about.

No doubt The Wall Street Journal has many readers, but how many there, paywalled, Ben, are word drudges?
And Geoffrey Pullum, co-founder of LL, your baby calls.
Or let Mark have to say,
And I only am escaped alone to tell thee?

It's written as a single sentence, but that might not suffice to make me read it as such.
"Rich and creamy! Your guests will never guess that this pie is light."
Where's that "matrix clause" now? All "syntax" is parataxis with varying degrees of politeness…

In terms of comprehension parsing, in this ‘garden path’ sentence, when the (speech or writing) parser (comprehender) processes the word ‘divers’, it must go back up the garden path and perform reanalysis to get the correct parse.

"After 700 years, 80-ton blocks from the long-lost lighthouse of Alexandria were recovered by underwater divers."
"Rich and creamy, this light pie will fool your guests."
It's just consistency of point of view. If you at least read over what you've just written you can fix it. The subject is the "eye" of the clause.

It doesn't help that "underwater" could be the end of "After 700 years" or the adjective for "divers".

It's clearly intended that the blocks spent "700 years underwater" because "underwater divers" would be a rather strange pleonasm.

I have been pondering whether people who dive onto nets or mats are 'overwater divers' (or 'non-water divers), and Olympics-style divers are 'over-and-underwater divers' (even though they are judged only for the overwater portion of their dive). Divers are a diverse group.

"Underwater diver" is entirely ordinary-sounding if I guess non-technical — it's more likely that "After 700 years underwater, …" was intended here just because this dangles marginally less awkwardly than "After 700 years, …" is all.
