Origin of combustionMiddle English, from Late Latin combustiō, combustiōn-, from Latin combustus, past participle of combūrere, to burn up, blend of com-, intensive pref.; see com– and ambūrere, to burn around (amb-, ambi-, ambi- + ūrere, to burn).
From Old French combustion, from comburere "to burn", itself from the intensifying prefix com- + the root burere (a faulty sep. of amburere "to burn around", itself from ambi- + urere "to burn, singe").
