thirteen 
c.1430, metathesis of O.E. þreotene (Mercian), þreotiene (W.Saxon), from þreo "three" + -tene (see -teen). Cf. O.Fris. thretten, Du. dertien, Ger. dreizehn. Not an unlucky number in medieval England, but associated rather with the customary "extra item" (e.g. baker's dozen). Superstitions began with association with the Last Supper, and the unluckiness of 13 sitting down together to dine (attested from 1695). Most of the modern superstitions (buildings with floor "12-A," etc.) have developed since 1890.
