The word's journey

Pronunciation

  • /ˈleɡo/, [ˈle.ɣ̞o][1]

Forms

lego (feminine lega, masculine plural legos, feminine plural legas)[1] Old Spanish also had leygo, and Old Leonese llego.[2][3]

Etymology

It is inherited from Old Spanish lego, inherited from Late Latin laĭcus (“not of the clergy”), which is from Ancient Greek λαϊκός (laïkós, “of the people; profane”), from λαός (laós, “people”).[4][5][6][1] Henríquez Ureña describes the change as a series of assimilations, the diphthong /ai/ passing through /ei/ to /e/, with the voicing of the /k/.[7] The learned doublet is laico, in common use in the 19th century.[4][5]

The same word is Portuguese leigo, Galician leigo, Old Leonese llego, Catalan llec and Italian laico.[3][8][9]

Earliest recorded meaning

Corominas's first record is in Berceo's Milagros de Nuestra Señora (1220–1250), where the word means a layman, as against a cleric.[4][5] Berceo's Santa Oria sets the two side by side: mucho buen lego, mucho buen ordenado “many a good layman, many a good ordained man”.[10]

Semantic evolution

The word was common in the Middle Ages, in Juan Manuel and Juan Ruiz among others, mainly as the opposite of clérigo.[4] Alfonso X's General Estoria speaks of clerigos & legos alike.[11]

Because only the clergy could read and write, the laity counted as unlearned, and the sense “ignorant, lacking knowledge of a subject” grew from this.[12] Covarrubias in 1611 said that a man is muy lego when he knows little of church matters.[13] The Diccionario de Autoridades gave three senses: a layman without the privileges of the clergy, the lay brother or lay sister of a religious house, and a person without learning.[14] Terreros added that it could mean dull or stupid.[15]

The law used the formula lego, llano y abonado for a guarantor who had no clerical or noble privilege and owned property.[16][17] In the Dominican Republic lego is used for a person of little intelligence.[18]
