What is "aminadi"

According to the Book of Mormon, Aminadi was a Nephite that lived in the Americas sometime before the time of Christ. He is mentioned briefly in the Book of Alma, and is notable in that he is a descendant of Nephi, and an ancestor (through at least three generations) of the prophet Amulek.

During a speech to the people of Ammonihah, Amulek states that Aminadi was known as a prophet that had "interpreted the writing which was upon the wall of the temple, which was written by the finger of God."
