Stymie

[William A Hupy]

To block, hinder or thwart. From Scottish, meaning a person who sees poorly. As understood by me this was originally used in golf when an opponents ball blocked the hole. I guess the other player couldn’t see the hole well enough so he was stymied.

Here's a rare case, a word that was done, but never made it to the dictionary. I didn't think that was possible. Here it is on the Agora, though.
