Forms

promíscuo (feminine promíscua, masculine plural promíscuos, feminine plural promíscuas)[1]

Etymology

It is borrowed from Latin prōmiscuus (“shared, common; mixed, indiscriminate”).[2][3][1] Nascentes calls it a learned word, from the Latin sense “used in common”.[4] The Latin adjective is formed from prō-, misceō (“to mix”) and the suffix -uus;[5][1] Tacitus and Gellius have the shorter form prōmiscus.[5][1] The verb goes back to *mi(k)skō, an inchoative present of Proto-Indo-European *meyǵ- (“to mix”).[1][6]

The same Latin word was borrowed as Galician promiscuo, Spanish promiscuo, Catalan promiscu, French promiscu and Italian promiscuo.[1][7]

Semantic evolution

Houaiss dates the word to 1671, and Cunha to the 17th century.[2][3] Bluteau glosses it as “confused, without order, without distinction”, with Livy's promiscua connubia for marriages made without distinction between noble and common families.[8] Feijó (1734) insists on the spelling promîscuo against promixcuo.[9] Morais (1813) adds grammar's nome promíscuo, a noun used for both the male and the female of a species, which Vieira also records; modern dictionaries mark it obsolete and use epiceno instead.[10][11][12][13]

From the mixing of what should be kept apart the word came to imply moral disorder, and in Brazil it is used of a person who has many sexual partners.[2][14][12]

Timeline

  • 1671 – first record.[2]
  • 1712–1728 – Bluteau defines promîscuo as confused and without distinction.[8]
  • 1734 – Feijó prescribes the spelling promîscuo.[9]
  • 1813 – first record of the derivative promiscuidade;[10] Morais records nome promíscuo.[3][10]
  • 1871–1874 – Vieira gives the sense “without distinction” and the grammatical term.[11]
