Sloth in Spanish: Perezoso, Oso Perezoso, and the Lazy Connection

Perezoso · noun (masculine) / adjective · peh-reh-SOH-soh

Sloth in Spanish is perezoso, a word that doubles as both the animal name and the adjective for lazy. The full name oso perezoso (literally 'lazy bear') reflects how early Spanish speakers perceived the slow-moving creature. The abstract noun pereza means laziness or the deadly sin of sloth.

Say peh-reh-SOH-soh with stress on the third syllable. All four syllables get equal weight except the stressed SOH. The r is a single tap, not a trill.

Vimos un perezoso colgado de un árbol en Costa Rica.

We saw a sloth hanging from a tree in Costa Rica.
