noun, masculine/oˈbiʝo/plural: ovillos
ovillo is masculine in Spanish.
ball (of wool); ball (of things tied up); pile, bunch
Inherited from Old Spanish oviello, loviello, from Late Latin lubellum < globellum, diminutive from Latin globus. The loss of initial /l/ may be due to absorption by a preceding article (el loviello > el oviello).
