Mormon

The term originates from the title of a sacred text, the Book of Mormon, first published in 1830 by the movement's founder, Joseph Smith. Smith stated that the book was a translation of ancient writings engraved on golden plates, compiled by a prophet-historian named Mormon. The name "Mormon" itself is presented within the narrative as a personal name, likely derived from Egyptian-based reformed Egyptian script used in the text. Consequently, the word was adopted from this foundational text to designate the members and attributes of the religious community that formed around its teachings, evolving from a proper noun into a common noun and adjective in English usage.

The word is a proper name adopted as a single lexical unit. It does not contain productive morphemes in English that can be segmented according to the rules.
