Etymology

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-.
