Saddam may be hung for all I know, but that won’t matter after he’s hanged.
The grammar hasn’t changed, as far as I know. But hung/hanged is a common mistake, and I’m not surprised if the newscasters make it - particularly if they’re speaking extemporaneously. If they’re reading, there’s not much of an excuse. I don’t know if TV stations have copy editors the way newspapers do, though.
I think it’s just been too long since anyone has been hanged around here that they figure it’s old usage or poor grammar. It sounds bad. It is bad, but it also sounds bad, grammatically and orally. The consonants jive - one’s way in the back and the other’s up front.
So is anything besides a person ever hanged? If pictures, meat, etc. all are hung and people are hanged, then it seems like not so much a grammar issue as a colloquialism issue.
From Monty’s link: "The historically older form hanged is now used exclusively in the sense of causing or putting to death: He was sentenced to be hanged by the neck until dead. In the sense of legal execution, hung is also quite common and is standard in all types of speech and writing except in legal documents. When legal execution is not meant, hung has become the more frequent form: The prisoner hung himself in his cell. "
But it is execution only by hanging by the neck, right? For example, Christ was hung from the cross, not hanged?
Interesting, I never thought about contexts like “being hung in effigy”, but it does sound right tha way. OTOH for a real, official hanging, only hanged sounds right.
Given the fact that, IIRC, execution by hanging is practiced nowhere in the Anglosphere, that usage will fossilize and remain in place.
