Long before "weird" meant strange, it meant becoming.
In Old English, wyrd comes from weorþan — "to happen, to occur, to become" (Stone, 2022). It wasn't a synonym for doom, and it wasn't a script waiting to be read out. It was the word for the process by which anything at all comes into being. A person's wyrd wasn't what had been written about them. It was what they were still becoming.
The same root gives us a second thread worth holding onto: Old English wyrd is twined with the ancestors of modern "worth" (Stone, 2022). Becoming and worth, tangled in the same word, from the start.
