Pronunciation

  • /ˈbobo/, [ˈbo.β̞o][1]

Forms

bobo (feminine boba, masculine plural bobos, feminine plural bobas)[1] Old texts also write bovo: Juan Ruiz has bova with the variant boba, and Nebrija writes bovo where Alonso de Palencia has bobo.[2][3]

Etymology

It is inherited from Latin balbus (“stammering”).[3][4][5][1] Wiktionary adds that sound symbolism influenced the form.[1] The REW lists the Spanish word under the Latin adjective but allows that it may come from an expressive root with ⟨bob-⟩.[6][3] Corominas thinks this possible but unnecessary.[6][3]

The Portuguese word bobo has a close /o/, where /ou/ would be expected, so Cornu proposed a Latin word for “child” instead, which the DCECH rejects on much stronger phonetic grounds.[3] Gonçalves Viana and Leite de Vasconcelos took the Portuguese word for a Castilianism, and the REW derives it from Spanish.[3][6] Cunha allows Castilian influence.[7] Corominas explains the vowel as a reduction of /ou/ before labials, and points to Mirandese búubo and the Galician noun bouba “jocular lie”, which keep the older diphthong.[3]

In the other languages the Latin word changed its meaning: Catalan balb means “numb with cold” and French ébaubi “dumbfounded”, while Italian balbo kept “stammering”.[3][8][6] The adjective Old Occitan bobs “foolish”, found once in 1318, and Sardinian bovu were taken from Castilian.[3][6] The Latin adjective is an expressive word: de Vaan reconstructs Proto-Indo-European *bl-bl- (“meaningless twaddle, stammering”), and the OLD calls it onomatopoeic.[9][10]

Earliest recorded meaning

Juan Ruiz's Libro de buen amor (1330–1343) uses bova for a foolish woman.[2] A Latin–Spanish glossary of about 1400 renders Latin bobus as bobo, and in 1490 Alonso de Palencia gives bobo among the Spanish equivalents of a Latin word for “witless, careless”, the first record the DCECH knows.[11][3]

Semantic evolution

In the Celestina (1499) the word also means “enthralled, carried away”: me traes boba con tus ofertas vanas “you have me dazed with your empty offers”.[11] Corominas notes the related sense “stunned with surprise” in Villalón and Cervantes de Salazar.[3] In the theatre of the Golden Age the bobo was the simpleton whose foolishness made the audience laugh, and Cervantes calls it the cleverest part in a comedy.[5][12]

Covarrubias derived the word from Latin bos, bovis “ox”, likening the fool to the slow ox, and the Academy repeated his view in its first dictionary; he also records a hollow headdress worn under the chin called bobo and the proverb a los bobos se les aparece la Virgen María.[13][14] Terreros gives bobo as the name of a seabird that lets sailors catch it by hand, and Salvá in 1846 a fish of American rivers, said to be named for how easily it is killed.[15][16] The Academy's 1884 etymology was a Latin babulus, later replaced by balbus.[17][5]

In Spanish America the word is recorded from 1535, for birds in Peru so tame they did not flee.[18] In Cuba it names a card game, the mona, and in the Canaries the shrub Nicotiana glauca.[19][20] The English word booby, first recorded in the 1590s, comes from the Spanish word.[21][22]
