Etymology

The word familiar traces back to Latin familiaris, meaning "of a household." Originally, it described domestic relationships or servants within a household. Over time, it broadened to denote closeness or intimacy (e.g., "familiar friends") and later evolved into its modern sense of "well-known." The noun form, referencing supernatural companions (e.g., witches' familiars), arose in the 16th century, metaphorically extending the idea of a close attendant.
