I found in a comic book an interesting example of an embedded interrogative that had Subject-Auxiliary Inversion (SAI): I'm not too sure what exactly is it that you're asking. Is this Standard English or a dialect thing? I know embedded SAI is found in Northern England, but this is presumably an American example. Are there any special environments in which we may find embedded SAI?
Inversion is sometimes found in AmE (but not normally in BrE) in contexts of strong question-orientation. Cf. also "Ed asked what had he done wrong" / "She wanted know was he ill".– BillJMay 9, 2022 at 11:10
If the embedded question is actually intended to solicit an answer, it can optionally invert to signal this pragmatically.– John LawlerMay 9, 2022 at 15:38
