As I watched one of my favorite TV shows the other night — “Imposters” — one of the characters mentioned that the word weird originally meant destiny.
I thought that was a bit weird and worth researching, and guess what? That was the exact meaning of the Old English word wyrd — fate or destiny.
It seems that Shakespeare started, or accelerated, the modern interpretation (with the help of the Scotch earlier), when he described the witches in Macbeth as weird.
Original usage of wyrd, however, was as a note, as wordorigins.com notes:
Weird is found in Beowulf (spelled wyrd) as a noun meaning fate or destiny:
Gæð a wyrd swa hio scel.
(Fate goes ever as fate must.)
Hie wyrd forsweop on Grendles gryre.
(Fate sweeps them away into Grendel’s clutches.)
