Etymology
The word 'asphyxia' has a precise medical origin in New Latin, directly borrowed from the Greek asphyxia, meaning "a stopping of the pulse." This Greek term is itself a compound, built from the negative prefix a- (without) and the noun sphyxis (pulse, heartbeat). The literal logic is therefore "absence of pulse." Over time, the medical understanding evolved, and the term's meaning shifted from the primary symptom (stopped pulse) to its most common cause, now denoting the pathological state of severe oxygen deprivation leading to suffocation. This etymological journey illustrates how a term for an effect came to signify its underlying cause.
