heathendom

Etymology

From Middle English hæthendom, from Old English hǣþendōm; equivalent to heathen + -dom. OED records a single attestation in the period between 1230 and 1840, a (nonce?) occurrence in J. Law, Proposals and reasons for constituting a council of trade in Scotland (1701, p. 233). Otherwise replaced by Middle English hethenesse in the later Middle English period and heathenism in the 17th and 18th centuries. Cognate with Dutch heidendom, Old High German heidentuom (German Heidentum), Old Norse heiðindómr (Swedish hedendom).
