People never want to use “drunk” correctly. “Hey! all the milk has been drunk!” People always want to say “drank” in sentences like that. I think it’s because “drunk” is so stigmatized as meaning intoxicated, that people don’t want to use it for anything else.
I wonder if the reason executed people have been “hanged,” not “hung,” is to prevent a similar thing from happening to “hung.” Also, a “hanged man,” and a “hung man” (not to mention a hangman) are very different things.
Fling, flang, flung-- I wouldn’t have believed this one, except I saw “flang” in some published stage directions of an O’Neill play. Now, I know published stage directions are just taken from the assistant director’s notes from the original production, but still.
