Pronunciation

  • Brazil: /ˈsĩ.nu/[1]
  • Portugal: /ˈsi.nu/[1]

Forms

sino m (plural sinos)[1] Houaiss records the spellings syno (1390), synno (1391) and ssyno (1393).[2] The form sino was also the medieval spelling of signo “sign”, used in that sense until the 16th century.[3]

Etymology

It is inherited from Latin signum (“sign, mark”), written Old Galician-Portuguese sino in the oldest texts.[2][4][1] Houaiss explains the word as the popular outcome of the Latin noun, a doublet of the learned signo and of senho.[2] Cunha calls it a semi-learned variant of the same word.[5] Wiktionary adds senha to these doublets.[1] The sense comes from the bell as the instrument that gives the signal for the hour of prayer.[2][4]

In Late Latin the noun itself came to mean “bell”: the REW notes that the sense is first found in Gregory of Tours, perhaps as a translation of a Greek word.[6][7] The same use survives in Galician sino, Catalan seny and Old Occitan senh, and through the Occitan compound tocasenh in French tocsin.[6][1][7]

The Latin word is derived either from Proto-Indo-European *sek- (“to cut”) or from *sekʷ- (“to follow”).[1] The OLD too connects it with secō (“to cut”).[8]

Earliest recorded meaning

A Latin document of 1101 already lists sinum among the goods of a church, together with books and a chalice.[3] The first vernacular records have the older sense “sign”: a charter of 1265 has meu sino “my sign”, the notary's mark, and others of 1282 and 1289 do the same.[3] The sense “bell” is frequent in the Cantigas de Santa Maria, as in mandou os sinos tanger “ordered the bells to be rung”.[3]

Semantic evolution

The Miragres de Santiago use the plural both for church bells and for small hand-bells.[3] In the sense “sign” the word was replaced by the learned signo, but it lingered in the phrase sino samão or sino salomão, the six-pointed star of two crossed triangles.[9][10] The early dictionaries gloss the bell with Latin cymbalum and tintinnabulum.[11][12] Barbosa (1611) also has Sineyro, the bell-ringer, and tanger os sinos “to ring the bells”.[11][12] Bluteau describes the bell as the instrument that calls Christians to church.[13]

From the bell's shape the word named a diving bell, recorded by Silva Bastos in 1912, and later an orchestral instrument of tuned metal tubes.[14][2] Silva Bastos also records the slang sense “a large glass of wine”.[14] The sino de correr was the bell that rang the hour for taverns to close and for Jews and Moors to go home.[2] The word passed into Kabuverdianu and Tetum as sinu and into Sinhalese.[1]

Usage notes

Houaiss and Aurélio have a separate, archaic sino “gulf, bay”, from Latin sinus (“curve, fold; bay”), which Houaiss dates to 1552; it is a doublet of seio and seno.[2][17][1] Vieira quotes it from Tenreiro's Itinerário in the phrase sino pérsico “the Persian Gulf”, and Morais (1789) defines it as a bay or inlet.[20][9]
