Etymology
The word 'medium' entered English in the late 16th century, directly from the Latin word 'medius', meaning 'middle'. The Latin term itself is traced back to the Proto-Indo-European root medhyo-, which also meant 'middle'. The core concept of being in an intermediate position or serving as an intermediary has remained remarkably consistent. Over time, this literal sense of a middle point or intervening substance broadened into its modern abstract meanings, encompassing any intervening agency, channel of communication, or material through which something is conveyed, from artistic media to spiritual mediums.
