IPA: /ˌɪn.kænˈdɛs.əns/
KK: /ɪnˈkændəsəns/
The state or quality of producing light as a result of being heated, often seen in objects like light bulbs or metal when they are very hot.
The incandescence of the light bulb illuminated the entire room.
Incandescence is formed from "in-" (meaning into or within), "candere" (meaning to shine or glow), and "-escence" (meaning the process of becoming). The word describes the process of becoming glowing or shining, particularly due to heat.
Think of something 'shining' ('candere') as it becomes 'within' ('in-') a state of glow — that's what incandescence means.
