I have been researching on multiple modal constructions, which is a feature used in the Southern United States. Unlike Standard English, this dialect allows more than one modal auxiliary per clause. For example, some speakers of this dialect may say, "You might could go to the store for me."
What I would particularly like to know is about verbal phrase ellipsis and subject-auxiliary inversion of the multiple modal sentences.
I would like to ask researchers on multiple modal constructions used in The Southern United States about the grammaticality or acceptability of the following sentences.
about verbal phrase ellipsis:
a. I might could should do that, and you might could should too. b. I might could should do that, and you might could too.
a. Rose might will can't come tomorrow, but Joe might will can. b. Rose might will can't come tomorrow, but Joe might will. a. Rose might will can come tomorrow, and Joe might will can too. b Rose might will can come tomorrow, and Joe might will too.
about subject-auxiliary inversion
a. Could I might should do that? b. Should I might could do that?
a. Will Rose might can't come tomorrow? b. Can't Rose might will come tomorrow?
