Wilson Gray on ADS-L on the 6th:
“She was lying on her back, when she was stabbed, in the prone position.”
He meant to say, “in the supine position,” of course.
There’s no “of course” here. No, that is almost surely not what the speaker meant to say; I’d wager he intended to say exactly what he did say. It’s just not what Wilson thinks the speaker should have said. (Or he’s mocking people who talk this way, though I failed to detect any raised eyebrows in what he wrote so briefly and dismissively.)
We have here a widespread vulgar confusion, a failure to distinguish
between inadvertent errors, things that are “wrong” for the person who produces them, and advertent errors, things that are ok so far as the producer is concerned but “wrong” from the point of view of at least some other people. (Faced with [the first], you call in the psycholinguist; faced with [the second], you call in the sociolinguist.) (Language Log link)
On top of that, Wilson has the sociolinguistic facts wrong, through a confusion between ordinary language and technical language: supine is a technical term for a bodily postion (lying flat on one’s back), used in certain specific domains (anatomy, sport, and shooting, in particular); in those domains, its counterpart (referring to lying flat on one’s belly) is prone, but in ordinary language, outside these specific domains, prone can refer to lying flat in general, and supine isn’t used at all.
The mistake here lies in assuming that technical, domain-specific (medical, botanical, technologcal, etc.) vocabulary is the true, correct, uniquely valid scheme for naming. From my 7/27/15 posting “Misleadingly named animals”, on zoological names:
The terminology “true fly” and “true bug” (etc.) here arises from the attitude that the naming practices of biologists are the only valid (true) naming schemes — what I’ll call technicalism. In the case of fly and bug, technicalism is remarkable from the historical point of view, since the specialized use of these nouns represents a decision to use perfectly ordinary vocabulary as technical terminology by drastically restricting its reference.
