credo m (plural credos)[1]
Etymology
It is borrowed from Latin crēdō (“I believe”), the first person singular present of the Latin verb, the first word of the Creed (⟨Credo in unum Deum⟩ “I believe in one God”), which became the name of the prayer.[2][3][4][5][1] The interjection is the same word.[6][1] The inherited form of the Latin verb is creio, from crer, and Wiktionary calls the two doublets.[1] Spanish credo is recorded from 1565 and French credo from about 1190.[7][8] The REW notes that the word passed from the Mass into the vernaculars.[9]
The Latin verb goes back to *krezdō and to Proto-Indo-European *ḱred-dʰeh₁- (“to place one's heart, to trust”), a phrase of the word for “heart” and *dʰeh₁- (“to put”); its cognates include creitid (“believes”).[10][1]
Earliest recorded meaning
Houaiss dates the noun to the 14th century, from Cunha's index of medieval Portuguese, in the sense of the Christian prayer.[2] Cunha's own first date is 1570.[3] The Vida de Santa Maria Egipcíaca, in a witness of 1431–1446, also has it.[11]
Semantic evolution
From the prayer the word came to mean the short time it takes to say it: the REW cites the Portuguese phrase em um credo “in an instant”.[2][9] It also names the part of the Mass that begins with the prayer, and a musical setting of it.[2][12] Houaiss notes that the senses “religious belief” and, by extension, a political or philosophical creed are much later.[2] Bluteau (1712–1728) still calls it a Latin word for the Apostles' Creed.[13] The old Caldas Aulete and Figueiredo (1899) have the senses “programme of a party” and the interjection of fright.[14][15] Michaelis calls the interjection popular.[16]
