This is the kind of resource that BOMC excels at making available. I recommend the video to anyone interested in Book of Mormon scholarship. The topic might seem a little arcane and narrow, but it's not. Carmack does a great job explaining why we have some of the odd grammar in the Book of Mormon text.
Here's the abstract:
"The grammar of the Book of Mormon has been naively criticized since its publication in 1830. The supposedly bad grammar is a match with language found in the Early Modern English textual record. Syntactic usage, especially past tense with did and the command construction, points only to that era. Book of Mormon language exhibits well-formed variation typical of the 16th and 17th centuries."
I'd like a transcript--maybe there is one that I don't know about yet--but for now the video is fantastic.
Go watch it.
