Word Watch 8, "weird"

Weird, as I've always used it, is an adjective; yet the first definition the OED gives is as a noun: "the principle power by which events are predetermined; fate, destiny." The plural form (werdys) refers to the Fates, "the three goddesses supposed to determine the course of human life." Then, there is the verb meaning "to preordain," which comes from the noun. Nowadays we have a slang verb "to weird out" meaning "to induce a sense of discomfort, alienation, strangeness." This definition comes closer to the usual way I use the adjective. As for the adjective, the first entry refers to the Weird Sisters from Macbeth--"Having the power to control the fate or destiny of human beings." It is not until the 3rd and 4th entries that the definitions come close to my original idea of weird--"out of the ordinary."
