IPA: /ˈspɪrɪt.ləs/
KK: /ˈspɪrɪtˌlɛs/
The condition of lacking energy, enthusiasm, or spirit.
After the long meeting, there was a sense of spiritlessness in the room.
Spiritlessness → It is formed from "spirit" (from Latin "spiritus", meaning breath or soul) and "-lessness" (meaning without). The word "spiritlessness" refers to the state of being without spirit or vitality.
Think of 'spirit' as representing life or energy, and '-lessness' indicating a lack of it — so spiritlessness means lacking that vital energy.
