Linguistic Origin & Historical Etymology

The term is a hybrid combination of the English prefix 'self-' (derived from Old English 'self') and the noun 'combustion' (derived from Latin 'combustionem', meaning 'a burning up', from 'comburere'). It emerged in scientific and medical literature during the 19th century to describe processes of oxidation that occur without an external ignition source.
