Describing something that does not contain lime, a type of mineral.
The limeless soil was ideal for growing certain types of plants that thrive without lime.
Limeless → It is formed from "lime" (from Old English *lim*, meaning a sticky substance or adhesive) and "-less" (meaning without). The word "limeless" means without lime or lacking the sticky substance.
Think of being 'without' ('-less') a 'sticky substance' ('lime') — that's what limeless means.
