Forms

leigo m (plural leigos)[1] Houaiss records leiga and leygo in the 13th century, leigos in the 14th and leyguas in the 15th.[2] Wiktionary lists leygo as an old spelling.[1]

Etymology

It is inherited from Latin lāicus (“of the people, lay”), written Old Galician-Portuguese leigo and Old Galician-Portuguese leygo in the oldest texts.[2][3][1] Houaiss and Aurélio call it the popular form of the Latin word, Nascentes a semi-learned one; the fully learned form is laico.[2][4][5] The Latin word, a term of the Church, is taken from Ancient Greek λαϊκός (laïkós, “of the people”), from λαός (laós, “the people”).[1][6]

The same Latin word is Galician leigo, Spanish lego, Catalan llec, French lai and Italian laico.[7][8] The Spanish word is recorded from Berceo on, and its learned laico came into common use only in the 19th century.[9]

Bluteau in 1712 already explained the word from the Greek for “people”, and quoted the Latin Bible's phrase for bread that is not consecrated.[10][6]

Earliest recorded meaning

A Latin charter of 875 already has the form leiga.[2] In the 13th century the Cantigas de Santa Maria tell of an abbot who left his office and tornou-se leygo, became a layman, and the Miragres de Santiago set os clerigos et os leigos side by side.[11]

Semantic evolution

The first sense is “not in holy orders”, said of people and things.[2][11] Houaiss notes that the noun first meant a lay servant of a convent, a sense the Priberam still gives for a convent servant without orders.[2][12] Cardoso in 1569 renders it with Latin prophanus.[13] Morais's dictionary of 1813 adds the sense “one who has no learning, ignorant”, from which came the modern “non-expert, unfamiliar with a subject”.[14][2] In Brazilian law a juiz leigo is a judge who is not a law graduate.[2]

  • c. 1438 – the Vida de Santa Eufrosina (witness 1431–1446).[15]
  • 15th century – the spelling leyguas.[2]
  • 1569 – Cardoso glosses the word with Latin prophanus.[13]
