The word "torch" originates from Old French torche (meaning "twisted thing"), derived from Latin torquēre ("to twist"). Early torches were made of twisted fibers soaked in flammable material. Over time, the term generalized to any portable light source, retaining its fiery connotation. The figurative sense ("symbol of enlightenment") arose from classical traditions (e.g., Olympic torch).
