IPA: /ˈtɜːrfləs/
KK: /ˈtɜrfləs/
Not having any grass or turf covering the ground.
The garden looked bare and turfless after the winter.
Turfless is formed from "turf" (from Old English *turf*, meaning a piece of grass-covered soil) and "-less" (meaning without). The word describes a state of being without turf or grass.
Think of being 'without' ('-less') a piece of 'grass-covered soil' ('turf') — that's what turfless means.
