Etymology

The adjective is first attested in the 1420s, the verb in 1526; from Middle English suffocat(e) (“deprived of air, suffocated”), borrowed from Latin suffōcātus, the perfect passive participle of Latin suffōcō (see -ate (verb-forming suffix) and -ate (adjective-forming suffix)), from sub- (“under, up to”) + fōx (“throat”, oblique stem in fōc-). Participial usage up until Early Modern English.
