What does suffocation mean?
Suffocation is the condition or result of being prevented from getting enough oxygen, usually because the airway is blocked, the nose and mouth are covered, or pressure is applied to the neck or chest. The word can describe the process of dying from this cause or the act of causing it. In medical, legal, and forensic writing, it often appears in phrases such as “death by suffocation” and “risk of suffocation.” It is related to asphyxiation, but asphyxiation is the broader medical term for oxygen deprivation, whereas suffocation more specifically suggests choking, smothering, or obstruction of breathing. Because the subject involves a potentially fatal interruption of breathing, suffocation is a formal term used in reports, court cases, public-safety warnings, and medical descriptions.

Where does suffocation come from?
Suffocation comes from the Latin verb suffocare, meaning “to choke” or “to suffocate,” formed from sub- and facere, “to make.” The English noun developed through Latin and French usage in the 16th century. The same Latin root appears in English words such as suffocate and suffocative, as well as in related forms in several Romance languages.
