Relating to or characterized by the absence of lips or lip-like structures, often used in anatomical or zoological contexts.
From Greek 'a-' (without) + 'liptos' (related to lips), influenced by Latin anatomical terminology. The prefix 'a-' means 'without' and combines with root words describing lip structures to indicate their absence.
This word appears mostly in scientific descriptions of creatures or organisms that evolved without mouth parts—like certain parasitic organisms that lost their lips entirely during evolution, which tells us how dramatically nature reshapes body structures when they're no longer needed.
