What Is the Origin of Arcana?
The word arcana has Latin roots. It comes from arcanum, which means a secret or mystery. Its deeper linguistic connection leads to the Latin arcanus, meaning hidden, private, or secret.

English adopted arcana around the 1590s. Writers historically used it to describe hidden knowledge, mysterious principles, and secrets of nature. Alchemists also used the term when discussing the mysteries of the natural and spiritual worlds. Etymology, Origin & Meaning+1
