The word "Mormons" most often refers to members of The Church of Jesus Christ of Latter-day Saints (LDS Church) because of their belief in the Book of Mormon, though members often refer to themselves as Latter-day Saints or sometimes just Saints.[14] The term "Mormons" has been embraced by others, most notably Mormon fundamentalists,[15] while other Latter Day Saint denominations, such as the Community of Christ, have rejected it.[16] Both LDS Church members and members of fundamentalist groups commonly use the word "Mormon" in reference to themselves.[17] LDS Church leaders have encouraged members to use the church's full name to emphasize its focus on Jesus Christ,[18][19] and have discouraged the use of the shortened form "Church of the Latter Day Saints", as well as the acronym "LDS", and the nickname "Mormons".[20][21][19]
The word "Mormon" is often associated with polygamy (or plural marriage),[22] which was a distinguishing practice of many early Mormons; however, it was renounced by the LDS Church in 1890[23] and discontinued over the next 15 years.[24] Today, polygamy is practiced within Mormonism only by people that have broken with the LDS Church.[25]
In the early days of the church the word "Mormon" or "Mormonite" was used to describe the religion in by those who were less familiar with the church.[26] The term "Mormonite" was used several times in derogatory works.[27][28]
