Synonym discussion

Sense: noun/1

All four words involve a dangerous loss of air, but they focus on different parts of the event. 'Asphyxiation' is the most formal and medical term, and it often appears in hospital, police, or legal reports. 'Suffocation' is the everyday word and can describe the same result in less formal language. 'Choking' is narrower, because it usually means that food or another object blocks the throat. 'Smothering' stresses air being shut out from the outside, for example by a pillow, thick smoke, or a plastic bag. A child who swallows a coin may be choking, while a person trapped in a sealed room may die from asphyxiation.

Etymology

Asphyxiation comes from 'asphyxiate', which was built on 'asphyxia', a medical word that reached English through Greek roots. The Greek source combined a negative element meaning 'without' with a word related to 'pulse' or 'throbbing'. In later medical use, the word came to describe the dangerous loss of breath and oxygen in the body. The ending '-ion' gives the modern noun for the state or process of dying because air cannot be taken in.
