What is the structure of might + verb (in past tense) called?
I might said it. (Instead of I might have said it.)
I might did it. (Instead of I might have done it.)
I might did say it. (Instead of I might have said it., with did as an auxiliary verb.)
The verbs said and did are not modal, and so these examples are not double modal. But I don’t know whether these are speech errors, and I myself might have said it (and it might not sound entirely unnatural). What is this structure?
I thought it would be nice to have a name to the structure when people discuss this type of construction, unlesse it’s No English at all but a form of (non)standard dialect.
Prior to this posting, I came across an article, titled might didn’t, about a similar structure of double modals. I was in hope of making a valid question for the Forum.
This type of structure is not listed in commonly available references, while it is also difficult for lay people to ascertain the facts that its usage is common in particular dialects.
I don’t think the study of its usage is particularly useful for English learners. Learners may get a wrong idea that English speakers in general are receptive to nonstandard usages.
