Question: What is the origin of the name Alma?
Answer: The Latin Alma is a name given to a woman. Is Alma also a semitic masculine name? Professor Yigael Yadin found, near the northwestern shore of the Dead Sea, an ancient land deed bearing the names of those who had leased property under Bari-Kokhba.
One of the names was “Alma, son of Yehudah.” Professor Yadin’s find suggests that Alma is a semitic masculine name meaning “youth” or “lad.”
