Etymology: "Acephalic" is built from two parts: the Greek prefix "a-", meaning "without," and "cephalic," from Middle French "céphalique," which came into English from Latin and Greek roots tied to the head. Its literal sense is "without a head," and it has been used of animals and body parts that lack one, though the word is applied just as often to structures that have no leading or top portion. The Greek prefix "a-" is the same negating element found in words like "atheist" and "anarchy," and it has been added to a wide range of Greek-derived terms. Here it attaches to "cephalic," which in English medical and anatomical writing refers to the head or skull. Combining the two gives a precise technical description rather than a poetic image.
