lipless

the word 'lipless' is a transparent english compound formed by combining the native english noun 'lip' with the equally native suffix '-less'. the old english root 'lippa' for 'lip' is of germanic origin, with cognates in other germanic languages. the suffix '-lēas', meaning 'devoid of', evolved from an independent old english adjective meaning 'free from' or 'false'. the compounding logic is straightforward and literal, directly describing the state of being without lips, a pattern common in english for denoting the absence of a feature.

Structure: lip (body part) + less (without) lip (from old english 'lippa', meaning a body part at the mouth); less (from old english '-lēas', an adjective-forming suffix meaning 'devoid of, free from').
