Suffocation \Suf`fo*ca"tion\, n. [L. suffocatio: cf. F.
suffocation.]
The act of suffocating, or the state of being suffocated;
death caused by smothering or choking.

with asphyxia. In the strict medico-legal sense it
signifies asphyxia induced by obstruction of the
respiration otherwise than by direct pressure on the
neck (hanging, strangulation) or submersion (drowning).
