IPA: /ˈlɪpləs/
KK: /ˈlɪpləs/
Describing something that does not have lips or a lip-like structure.
The fish is lipless, making it easier for it to catch prey in its environment.
Lipless → It is formed from "lip" (from Old English "lippa", meaning the edge or border of something) and "-less" (meaning without). The word "lipless" describes something that is without lips or lacking in lip-like features.
Think of something that is 'without' ('-less') the 'edge' or 'border' ('lip') — that's why lipless means lacking lips.
