IPA: /kænˈdɛsənt/
KK: /kænˈdɛsənt/
Emitting light or glowing due to high temperature; very bright or shining.
The candescent light from the fire illuminated the entire room.
Candescent is formed from "candere" (meaning to shine or glow) and the suffix "-escent" (meaning becoming or in the process of). The word describes something that is becoming bright or glowing, particularly in reference to heat or light.
Think of something 'shining' ('candere') and 'becoming' ('-escent') bright — that's why candescent means becoming bright or glowing.
