loco (feminine loca, masculine plural locos, feminine plural locas)

1. crazy, mad, insane
   • c. 1280, Alfonso X, General Estoria, tercera parte, (published by Pedro Sánchez-Prieto Borja and Bautista Horcajada Diezma, 1994, Madrid: Gredos):

     Yo só muy loco entre los omnes, e la sapiencia d'ellos non es comigo, mas la de Dios; ca la que yo é non me la dieron ellos si non Dios.

• Spanish: loco

loco

1. first-person singular present indicative of locar

• IPA^(key): /ˈloko/ [ˈlo.ko]

• Audio (Colombia):

  (file)

• Rhymes: -oko
• Syllabification: lo‧co

Inherited from Old Spanish loco, perhaps from Andalusian Arabic لَوْقَاء (láwqa), from Arabic لَوْقَاء (lawqāʔ), feminine singular form of أَلْوَق (ʔalwaq, “stupid”),[1] by reinterpreting the final Andalusian Arabic -a as the Ibero-Romance -a and back-forming the masculine with -o. Edward Roberts thinks the term is related to Arabic لَاق (lāq, “to soften”),[2] but this verb is of root l-y-q, not l-w-q like أَلْوَق (ʔalwaq). Alternatively, derived from Ancient Greek γλαυκός (glaukós, “clear”). Compare Portuguese louco and Sicilian loccu.
