Where does incandesce come from?
The word comes from Latin incandescentem, the present participle of incandescare, meaning “to become glowing hot.” Its elements combine in- with the intensive force of candere, “to glow, shine, or burn,” yielding the idea of being set alight by intense heat. English acquired the form in the early 19th century, when it was associated especially with heated materials and the development of incandescent lighting. The same Latin root also underlies “incandescent” and “incandescence.”
