ETYM Latin crematio.
Disposal of the dead by burning. The custom was universal among ancient Indo-European peoples, for example, the Greeks, Romans, and Teutons. It was discontinued among Christians until the late 19th century because of their belief in the bodily resurrection of the dead. Overcrowded urban cemeteries gave rise to its revival in the West. It has remained the usual method of disposal in the East.
The incineration of a dead body.
ETYM Late Lat. incineratio: cf. French incinération.
The act of burning something completely; reducing it to ashes.
