The original dictated version of the Book of Mormon contains 12 examples of complex finite cause syntax such as 1 Nephi 17:46:
he can cause the earth that it shall pass away
Stanford Carmack summarizes the significance of this:
This is not King James language or currently known to be pseudo-archaic language (language used by modern authors seeking to imitate biblical or related archaic language), but it does occur in earlier English, almost entirely before the year 1700. In the Book of Mormon, the syntax is always expressed with the modal auxiliary verbs should and shall. Twenty-five original examples of this specific usage have been identified so far outside of the Book of Mormon (not counting two cases of creative biblical editing — see the appendix). The text’s larger pattern of clausal verb complementation after the verb cause, 58 percent finite in 236 instances, is utterly different from what we encounter in the King James Bible and pseudo-archaic texts, which are 99 to 100 percent infinitival in their clausal complementation. The totality of the evidence indicates that Joseph Smith would not have produced this causative syntax of the Book of Mormon in a pseudo-archaic effort. Therefore, this dataset provides additional strong evidence for a revealed-words view of the 1829 dictation.– Stanford Carmack – The Book of Mormon’s Complex Finite Cause Syntax
Carmack has found that complex finite cause syntax has not been found to occur in:
If Carmack has not encountered any text that has sustained heavily finite verb complementation, where did Joseph Smith get this from and how did he achieve it while dictating?
