Etymology: Apnoeic is a medical adjective built from two parts: "apnea," a pause in breathing, and the suffix "-ic," meaning "relating to" or "having the character of." The base word "apnea" comes from the Greek "apnoia," formed from "a-," meaning "without," and "pnoia," meaning "breathing" or "blowing." The Greek root also gives us "pneumonia" and "pneumatic," which share the same sense of air and breath. The suffix "-ic" arrived through a long chain of borrowing. It passed from Latin "-icus" into Old French "-ique," then into Middle English as "-ik," and finally took its modern English spelling "-ic." Words built this way, like "public" or "music," follow the same route. The spelling "apnoeic" keeps the "oe" that appears in Greek-derived medical terms, while "apneic" drops it. Both forms are in use, and both describe the same thing: a condition of breathing with pauses, such as the interrupted breath seen in sleep disorders.
