The story
Learned borrowing from Medieval Latin ānnulus, a misspelling of Latin ānulus (‘ring, especially one worn on a finger’), from ānus (‘ring’) (possibly from Proto-Indo-European *h₁eh₂-n-o- (‘ring’), from an uncertain root) + -ulus (diminutive suffix).uncertain The source flags this step as uncertain. The plural form annuli is a learned borrowing from Medieval Latin ānnulī.
