Language Log

The Microsoft Manual of Style tells us not to use once as a subordinator because it could lead to ambiguity. Specifically, from the 1995 edition:

once
To avoid ambiguity, do not use as a synonym for after.

Correct
After you save the document, you can quit the program.

Incorrect
Once you save the document, you can quit the program.

(That's the entire entry.) Ambiguity? Stop a moment and try to concoct an English sentence where subordinator once could be taken to be something else. It can be done — see below — but it's not easy, and I doubt that examples like the ones below were what the MMoS folks had in mind.

Instead, I think they were concerned about the fact that once has three primary uses and that readers (especially readers who are not native speakers of English) might not understand which one was intended until partway into the sentence: TEMPORARY POTENTIAL AMBIGUITY (TPA). (I'll take up the concern for non-native speakers in a later posting.)

Here at Language Log, we don't just sit around unravelling the mysteries of by-topicalization, stress-timing, resumptive pronouns, and the like. We have our playful sides: cartoons, "lost in translation" examples, Cupertinos, fun with taboo avoidance. Here's today's little amuse-bouche (or, if you prefer, amuse-gueule), which came to me originally on a card from a friend: a photo of a sign on a platform at the Penrith (English Lake District) railway station. The card was a grainy print-out, but here's a much better image:

An invitation from Mark Dingmanse:

I just posted a piece on Many Eyes, a nice text visualization tool which I have fed some Siwu texts.

Now this is an open access tool with an interesting philosophy: "Many Eyes is a bet on the power of human visual intelligence to find patterns. Our goal is to "democratize" visualization and to enable a new social kind of data analysis."

I would like to test this philosophy in a peculiar way: by seeing if readers can come up with some kind of account of the functions of the Siwu word 'ne' *only by looking at the patterns* here.

Would you like to join all my eye and Betty Martin in some pattern hunting?

For more discussion, see Mark's post at The Ideophone, "Visual corpus linguistics with Many Eyes", 6/14/2008.

Almost a year ago, I posted here (well, at the old LL site) about a new peer-reviewed, open access journal affiliated with the Linguistic Society of America. The journal is called Semantics and Pragmatics (S&P), and I'm coeditor, together  with Kai von Fintel. The big news today is that we have published our first article, and it's a doozy – Donkey anaphora is in-scope binding, by Chris Barker and Chung-chieh Shan. To give Language Log readers a picture of some of what interests formal semanticists I'll fill you in with a little background on the paper – abstruse stuff, but it has applications. Then (and I hope you'll excuse the awkwardness of me slapping my own back, but who else is gonna do it?) I'll give you an update on how S&P is doing.

You're asked:

(1) Do you mind if I ask you a question?

How do you respond? There's a complexity here, no matter what your opinions about question-asking are. The problem is that (1) has the form of a yes-no question (about what the addressee's sensibilities are) but also conveys a request (for the addressee to allow the questioner to perform an action). An affirmative response to the yes-no question is a negative response to the request, and vice versa. Oh dear. (Actually, there's more.)

Hesitant though I am to take on still more uses of or (most recently discussed here) — this could quickly become an endless chain of fascinating data — here's one that at first is puzzling, until you figure out what people are trying to do with it. It came from Benjamin Massot, a French linguist currently living in Germany, who noticed signs like the following in lifts (or, as we say in American English, elevators):

French: capacité: 320kg ou 4 personnes

German: Tragfähigkeit: 320kg oder 4 Personen

In English, 320 kg or 4 persons. Massot tried at first to figure out who (the lift company or the users of the elevator) would be declared responsible in case of an accident, for various combinations of weights, numbers of people, and interpretations of or, but eventually concluded (correctly, I think) that in this context a limit of "320 kg or 4 persons" just meant 320 kg.

The saga of English or (last discussed on Language Log here) continues in my e-mail, with several pointers to literature (taking us away from traditional logic) and possibly relevant data.

In my posting on and/or, I gave an informal (but precise) account of what I take to be the semantics of expressions of the form X₁ or X₂ … or X_n, where or is understood exclusively: the disjunction is true if and only if exactly one X_i is true and the rest are false. (Compare the inclusive understanding, where the disjunction is true if and only if at least one X_i is true.) My inbox is now filling up with mail from people explaining to me that I'm wrong about the semantics of exclusive or. Well, actually, they're telling me that I'm wrong about the semantics of the binary logical connective of exclusive disjunction + (or however you want to represent this logical connective). I'm perfectly clear about the semantics of +, but that's not what I was talking about.

Language Log brings little surprises into my life — this week, the report by Geoff Pullum that there are people who believe that the English conjunction or is always understood exclusively (so that and/or and or both might be useful expressions to have around, to convey an inclusive reading).  Geoff countered with an argument that the meaning of or is in fact just inclusive disjunction, though the conjunction can be used to convey exclusivity via conversational implicature.  

The usage literature largely agrees with this position, and so and/or is widely (but not universally) reviled, as unnecessary. But there's more to the story.

Does and/or mean "and and or", or "and or or"? That is, if I say I am interested in A and/or B, do I mean I'm interested in A and B and I'm interested in A or B, or do I mean that I'm interested in A and B or I'm interested in A or B? (You may want to say that it means I'm interested in A and B and/or I'm interested in A or B; but in that case I repeat my question.)
