The Spanish word 'huarache', meaning a type of rustic sandal, comes from the Purépecha word 'kuarache', which also meant 'sandal'. Purépecha is an indigenous language family of Mexico, particularly spoken in the state of Michoacán. This is one of many words that Spanish borrowed from indigenous American languages during the colonial period.

There are no simpler or more common Spanish words that share the same etymology, as this word was borrowed directly from an indigenous American language.

The English word 'huarache' is borrowed directly from Spanish and refers to the same type of traditional Mexican sandal. While this word exists in English, it's primarily used when specifically referring to this style of Mexican footwear.
