IPA: /ˈsiːdləs/

Not having seeds or having very few seeds that are hard to notice.
I prefer seedless grapes because they are easier to eat.
Seedless → It is formed from "seed" (from Old English "sǣd", meaning the reproductive part of a plant) and "-less" (meaning without). The word "seedless" means without seeds, typically referring to fruits or plants that do not produce seeds.
Think of a fruit that is 'without' ('-less') 'seeds' — that's why seedless means it has no seeds.
