IPA: /ˈflaʊərləs/
KK: /ˈflaʊərləs/
Describing something that does not have flowers or is lacking in flowers.
The garden looked bare and flowerless during the winter months.
Flowerless → It is formed from "flower" (from Old English *flōwre*, meaning the reproductive structure of a plant) and "-less" (meaning without). The word "flowerless" means without flowers or lacking flowers.
Think of a plant that is 'without' ('-less') its 'reproductive structure' ('flower') — that's why flowerless means lacking flowers.
