Forms

santo (feminine santa, masculine plural santos, feminine plural santas, comparable, comparative mais santo, superlative o mais santo or santíssimo, diminutive santinho)[1] Houaiss records santo and sanctos in the 13th century, sante in 1391 and sãcto, ssãtas in the 14th century.[2] The Crónica Geral writes both sancto and santo.[3] Before the name of a saint the word is shortened to são (medieval san, sam): São Pedro, Old Galician-Portuguese San Clemente.[4][5][6][7] Houaiss dates the shortened form sam to 1193 and são to the 13th century.[4]

Etymology

It is inherited from Latin sānctus (“holy, sacred”), written Old Galician-Portuguese santo and Old Galician-Portuguese sancto in the oldest texts.[2][8][9][3] Houaiss notes that in Ecclesiastical Latin it was also a noun, “one of the blessed”.[2] Nascentes cites the reduced spelling santu from a Latin inscription (CIL II, 2395).[10]

The same Latin word is Galician santo, Spanish santo, Catalan sant, French saint, Italian santo and Sardinian santu.[11][9] Spanish has a shortened san beside it, as Portuguese has são.[11]

The Latin adjective is the past participle of sanciō (“to ratify, make sacred”).[12][13][2] Wiktionary takes it back through *sanktos and *sankiō to Proto-Indo-European *seh₂k- (“to sanctify, make a treaty”),[14] while its Portuguese entry names *sān- (“healthy, happy”) instead.[9]

Earliest recorded meaning

The 13th-century records are religious: the Cantigas de Santa Maria have a Virgen santa “the holy Virgin”, O sant'ome “the holy man” and Todo-los Santos que son no ceo “all the saints in heaven”.[3][8] The Crónica Troiana uses it of a pagan temple, o tenplo era santo aa honrra de apollo “the temple was holy in honour of Apollo”.[3]

Semantic evolution

Bluteau (1712–1728) explains that before the Church took up the name, Latin sanctus meant what was protected and guarded from harm, such as the walls and gates of a city.[15] Cardoso (1569) glosses the noun as “a good man”, and Morais (1789) records the military sense, the password given to the sentries.[16][17]

Houaiss gives the extended senses “useful, effective” (a remedy) and “someone who feigns innocence”, and the use of the noun for the image of a saint.[2] In Brazil santo is also the name for an orisha in the Afro-Brazilian religions, with the phrases fazer o santo and cair no santo for initiation and trance.[2][9][18] The word passed into Indonesian as santo and into Kadiwéu as xaanto.[9]

  • 13th century – first records of santo.[2][8]
  • 13th century – the Cantigas de Santa Maria use it of the Virgin and of the saints.[3]
  • 1391 – the form sante.[2]
  • c. 1400 – first record in the CTA corpus, in the Santiago fragment of the Flos Sanctorum.[19]
  • 1569 – Cardoso glosses the noun as “a good man”.[16]
  • 1712–1728 – Bluteau discusses the pre-Christian Latin sense.[15]
  • 1789 – Morais records the military password.[17]

Usage notes

Before a saint's name beginning with a consonant the shortened form são is used (São Pedro, São Paulo), and santo before a vowel (Santo António); the original Aulete notes the exceptions Santo Tirso and Santo Cristo.[23][24] The shortened form is a different word from the adjective são “healthy”, which comes from Latin sānus.[4][25]

The proverb santo de casa não faz milagre says that people's merits go unrecognised at home, and a santo do pau oco “saint of hollow wood” is a hypocrite, from the hollow wooden images once used to smuggle gold and diamonds.[2][26]
