The state of not feeling happy or joyful; a feeling of sadness or emptiness.
After the loss of her pet, she was filled with joylessness for weeks.
Joylessness → It is formed from "joy" (from Old French *joie*, meaning happiness or delight) and "-lessness" (meaning without). The word "joylessness" means the state of being without joy or happiness.
Think of 'joy' as happiness and '-lessness' meaning without — so joylessness is the absence of happiness.
