I’m putting killy here because it’s new to me, and in a sentence that I like, however I’m not sure this is really a word. I can’t find a definition for it anywhere that makes sense. All I could find was an alternate spelling of killie, which is a kind of fish, but that doesn’t fit with the word’s use.
Crewel is more clear – slackly twisted worsted yarn used for embroidery
Here’s the sentence, still from The Orchard Keeper:
“And the sun running red on the mountain, high killy and stoop of a kestrel hunting, morning spiders at their crewelwork.”
