What does altern mean?
"Altern" is a rare English noun referring to a person who acts in place of another — a substitute, deputy, or stand-in who may be called upon when the primary holder of a duty or office is unavailable. The word derives from the Latin alternus, meaning "one after another" or "by turns," the same root that gives us the far more familiar "alternate" and "alternative." In practice, an altern might be appointed to attend a meeting, serve on a jury panel, or fill an official role should the principal be unable to do so. Although the word is now largely archaic, appearing mainly in older legal, civic, and organizational texts, it remains a precise term for someone designated as a backup. Modern readers will more often encounter its relatives "alternate" and "substitute," but "altern" preserves a compact, elegant way of naming the person who waits in the wings, ready to step forward when needed.
nounA person who acts in place of another; a substitute or deputy who takes turns with others in performing a duty.
- A person who substitutes for or takes the place of another, especially in an official duty or role.
"The committee appointed an altern to attend the conference should the delegate fall ill."
"The judge selected an altern to serve if any juror was dismissed."
"Each guild member served as altern, ready to step in when the presiding officer was absent."
The standard plural simply adds -s.
"Several alterns were on hand in case the elected delegates withdrew."
Barely known today, "altern" is a centuries-old noun for a stand-in — proof that even English's quietest corners have words for being second in line.

Etymology of altern
"Altern" comes from the Latin alternus, meaning "by turns" or "one after another," itself formed from alter, "other." It entered English in the medieval period through legal and administrative usage, where it denoted a substitute or deputy acting in rotation with another. It shares this Latin root with "alternate," "alternative," and "altercation," all of which preserve the sense of otherness or taking turns.
