acnestis

From Late Latin acnestis, from Koine Greek ἄκνηστις (áknēstis, “spine”), from κνῆστις (knêstis, “spine, cheese-grater”), or from ἀ- (a-) + -κναίειν (-knaíein, “grate, scrape, scratch”) (only attested in compounds), or from incorrect segmentation of κατὰ κνῆστιν (katà knêstin, “on the spine”) (see Homer, Odyssey 10.161), ultimately from Proto-Indo-European *kneh₂-.^[1]

     Excoriations are typically linear and occur where the patient can reach with his hands. […] The middle of the back is typically spared, although with a back scratcher, this rule loses value. This pattern of sparing has been called the reverse butterfly sign; the Greek word for the area that cannot be reached is acnestis.

     In what has to be the longest post-election season in living memory, the last five months have felt like an acnestis upon our collective soul; like that little patch of skin on our backs that we just can't reach to scratch ourselves. It's irritating. It's annoying. It's left us reaching and spinning around in circles.

     I nudged Winston [a cat] to one side of his chair and sat down beside him. I scratched the spot between his shoulders, the acnestis that animals can't scratch by themselves, and he looked up at me and smiled.

     Acnestis (n.) On an animal, the point of the back that lies between the shoulders and the lower back, which cannot be reached to be scratched. I am very glad I found this word early in my reading of the OED – the fact that there existed a word for this thing which previously I had been sure lacked a name was such a delight to me that suddenly the whole idea of reading the dictionary seemed utterly reasonable.
