Elder
- The title for a male full-time missionary, always used with his last name (e.g. Elder Smith) for the entire length of his mission.
- Also an office in the Melchizedek Priesthood, and part of the title for certain Church leaders known as General Authorities.
For a missionary, "Elder" completely replaces first names — companions who spend nearly every waking hour together for months may never once use each other's given name. The word can be confusing to outsiders because a nineteen-year-old missionary and a silver-haired Church leader can both be called "Elder," and the plural "Elders" is a common shorthand for the young male missionaries working in an area. Female missionaries are instead called Sisters.
