A person who studies, practices, or is knowledgeable about arcane or esoteric knowledge; someone initiated into secrets or mysteries.
From arcanum or arcane + -ist suffix (indicating a person engaged in a specific practice or having specific knowledge). The term suggests expertise in hidden or secret knowledge.
Arcanist became a popular fantasy term (think video games and D&D) to describe wizards and occultists, but historically it referred to real people who claimed knowledge of secret sciences, alchemical mysteries, and hidden wisdom traditions.
