the term 'sublimation' originates from the latin verb 'sublimare,' meaning 'to lift up' or 'to elevate.' this verb itself is built from 'sub,' suggesting 'up from below,' and 'limen,' meaning 'threshold,' thus painting a picture of raising something past a boundary. in medieval alchemy, it described the process where a solid is heated and appears to vanish, rising up as a vapor, bypassing the liquid state—a literal elevation past the threshold of ordinary phase change. this concrete physical concept was later adopted into psychology by sigmund freud to metaphorically describe the elevation of primal impulses into socially acceptable activities, completing its journey from a literal to an abstract meaning.
