Entry: pendentive (adj.)
In context: "And Steeply raised his bare arms and held them out and crossed them, maybe as if signalling for distant aid; this made X's and pendentive V's over much in the city Tucson."
Definition: Each of the concave curved triangles lying between the arches supporting a dome, cupola, etc., and the baseline of this structure; an analogous curved region between the groins of a vaulted roof, etc.
Other: I chose this word not only because it was unfamiliar, but because it has a wonderful rhythm - try saying it aloud and savoring it. Isn't it fantastic?
To be honest, though, I'm so excited to get to the next word I'm just going to cut it clean now.
