“A Pedro no le mola nada hablar conmigo de su cerda. Está muy enamorado y no le gusta que me ría de él.” — Pedro doesn't like talking to me 'bout his bitch. He's very much in love and doesn't like me laughin' at him.
Disputed. Perhaps from Late Latin setula, diminutive of Latin sēta, saeta (“thick hair”) (compare Italian setola (“bristle”)), but the initial and the liquid would be irregular. Anders proposes a source in Vulgar Latin cirra (“lock, tuft of hair”), from Latin cirrus, influenced by saeta. Also compare Aragonese cerra and Basque zerri (“pig”).
