Pronunciation

  • /ˈba.t͡ʃo/, [ˈbaːʃo][1]

Forms

bacio m (plural baci)[1] Old Italian forms include bascio, basio, baso and bagio.[2][3][4]

Etymology

The kiss is inherited from Latin bāsium (“kiss”).[3][5][6][1] The Latin word first appears, with the verb basiāre, in Catullus, who was from Verona, and that is why it is often thought to be a Celtic loan.[3][7][8] Its erotic sense set it apart from Latin ōsculum, but in Imperial Latin it became the ordinary word, replacing that noun and sāvium.[7][9] De Vaan also notes the many words for “kiss” in other languages built on Proto-Indo-European *bu- with a sibilant, which point to a sound-imitative origin.[7][1]

The word survives everywhere in Romance except French and Romanian: Friulian bâs, Occitan bais, Catalan bes, Spanish beso, Portuguese beijo and Sardinian basu.[5][9][10] In the South Italian dialects the word fell together with the outcome of Latin vas (“vessel”) and was replaced by derivatives.[8][10] The old spelling with ⟨sc⟩ beside ⟨c⟩ shows the hesitation between /tʃ/ and /ʃ/ in rendering Latin /sj/.[11]

Earliest recorded meaning

The first record is bascio in Rinaldo d'Aquino, in the 13th century, for the kiss given out of love;[3][2][12] Zingarelli dates the word to about 1261.[3][2][12] The spelling bacio appears in Cecco Angiolieri before 1313.[3]

Semantic evolution

Old Italian already distinguished kisses of love, of family affection, of respect and submission, of peace, and the kiss given to the ground of a holy place; the bacio di Giuda echoes the Gospel story of Judas's betrayal.[2][3] Tommaseo records the Tuscan proverb bacio di bocca spesso cuor non tocca (“a kiss of the mouth often does not touch the heart”).[13]

Modern Italian ends letters with baci or baci e abbracci and has many fixed phrases: bacio della buonanotte, bacio della morte, malattia del bacio (mononucleosis), and colloquial al bacio “perfect”.[6][14][12] Bacio is also a sweet: the bacio di dama and the chocolate with a hazelnut first sold as a brand name by the Perugina company.[14][15]

Pronunciation

  • /baˈt͡ʃi.o/[1]

Forms

bacio (feminine bacia, masculine plural bacii, feminine plural bacie)[1]

Etymology

The adjective “north-facing” is inherited from Vulgar Latin *opacīvus (“shady”), a Vulgar Latin derivative of Latin opācus (“shady, dark”).[3][5][6][1] It is stressed on the ⟨i⟩.[14][15] The /b/ for /p/ is due to northern Italian dialects, and the first vowel was taken as part of the article: “l’obacìo” became “lo bacìo”.[5][16] Related dialect forms are Lombard vag, Romagnol beg and Piedmontese übak, and Old Italian ombaco has its ⟨m⟩ from ombra.[10][17][8] Across the Alps the same Latin word gave Occitan ubac and Catalan ubac.[10][8]

The origin of the Latin adjective is unknown; de Vaan rejects the old comparison with Sanskrit and Old Church Slavonic words meaning “turned away” and suggests, only as a possibility, a compound with the root of Latin vacuus.[7][1]

Earliest recorded meaning

The TLIO's first record is the Florentine Libro segreto di Giotto (1308–1330).[2] DELI's first records are Luigi Pulci (before 1484) for a north-facing place and Giovan Battista Tedaldi (16th century) for the adjective.[3]

Semantic evolution

The word is Tuscan and mostly agricultural, the opposite of solatio “sunny”: Crescenzi's translation already uses a bacìo “facing north”, and Bernardo Davanzati writes of plums that thrive in luoghi murati e bacii (walled and shady places).[18][13][5] Pascoli and D'Annunzio revived it as a literary word.[8][18]

Timeline

  • 1308–1330 – Bacìo appears in the Libro segreto di Giotto.[2]
  • Before 1484 – Luigi Pulci uses it for a north-facing place.[3]
  • 16th century – Giovan Battista Tedaldi uses it as an adjective.[3]

Meanings

Adjective

  1. (regional, rare) shady, not reached by the sun because it faces north: un pendio bacìo.[6][14][12]

Noun

  1. (regional) A north-facing, shady place, a bacìo, facing north.[6][12][19]
