Attestations from sources in English: 

"The words '-yol' and '-yollo,' literally 'heart' but often used for the mind, the emotions, and volition, figure in a large number of Nahuatl idioms. You will find a group of eleven of them in Molina under Noyol and Noyollo."
James Lockhart, Nahuatl as Written, 2001, 156.
