IPA: /ˈreɪləsnəs/
KK: /ˈreɪləsnəs/
A state or condition where there is no light or brightness, resulting in complete darkness.
The cave was filled with raylessness, making it impossible to see anything.
Raylessness → It is formed from "ray" (from Old English *rēg*, meaning a beam of light) and "-lessness" (meaning without). The word "raylessness" means the state of being without rays or light.
Think of being 'without' ('-lessness') 'rays' — that's why raylessness refers to a lack of light.
