Forms

búho m (plural búhos)[1] Old Spanish had bufo beside the more common buho, and bufo is still used in Aragon;[1] Juan Manuel also has buhón.[2] The spelling buho without the accent is also found.[1]

Etymology

It is inherited from Vulgar Latin bufo (“owl”), the Vulgar Latin form of classical Latin būbō, through Old Spanish bufo.[2][3][4][1] The form with ⟨f⟩ is found in Latin glosses and in manuscripts of Isidore, and one gloss has būfus.[2][1] Corominas explains that Spanish kept the Latin nominative rather than the accusative bufonem, and that the ⟨f⟩ between vowels was not voiced because the name was felt to imitate the bird's call.[2] The accusative did survive in Upper Aragonese bobón, with voicing, and in Juan Manuel's buhón.[2]

The same Latin word is Portuguese bufo, Galician bufo and Italian gufo.[2][5][6] An Arabic name of the owl used by an eastern author of the 10th century is probably an independent imitation of the cry, as Berber and other languages have similar names.[2]

The Latin noun imitates the owl's hoot, like Ancient Greek βύας (búas) and an Armenian բու (bu).[7][1][8] De Vaan treats it as a reduplicated form.[7]

Earliest recorded meaning

The first record is in the Moamín, a book on hunting animals translated by Abraham of Toledo (1250, in a copy of the second half of the 13th century), on what to feed falcons: la carne del búho es mala “owl's meat is bad”.[9] About the same time the Poridat de las poridades calls a man malauenturado como buho “ill-fated as an owl”, and Alfonso X's Espéculo lists los buhos & las lechuzas among the birds that hunt by night.[9] Corominas's own first record is in Alfonso X.[2][3]

Semantic evolution

As in Latin, the owl was a bird of ill omen: Alfonso X's Estoria de España (c. 1270) speaks of the owl as messenger of death.[9][8] The derivative buharro, a bird of prey like the owl, is first found in the 15th century and in Nebrija.[2][3]

The DRAE of 2001 already had the colloquial sense “unsociable person”; the DLE has added “night bus”, a Spanish name for the city buses that run during the night.[10][4][11] Wiktionary also records a colloquial sense “informer”.[1] In zoology Moliner keeps the name for the eagle owl, Bubo bubo, and notes that it is commonly given to all nocturnal birds of prey with ear tufts.[11]

Timeline
