Cognate to Sanskrit ककुद् (kakúd, peak, summit, point; head, chief; hump, projection; palate, tongue), which similarly preserves the original sense of projection in any direction, and the particular sense of the humped shoulders of an animal. The semantics of the denominal verb are influenced by acūmen.[1]
