credo m (plural credos)[1]

Etymology

It is borrowed from Latin crēdō (“I believe”), the first person singular present of the Latin verb, which is the first word of the prayer.[2][3][1] In Medieval Latin it was already an indeclinable noun, “creed”.[4] Meyer-Lübke notes that the word passed from the Mass into the Romance languages.[5] French credo is recorded from about 1190.[6] The same verb gave by inheritance creer, whose first person creo “I believe” is its doublet.[1][7]

The Latin verb goes back to *krezðō, from *ḱred-dʰeh₁- “to place one's heart”, that is “to trust, believe”, a phrase of *ḱḗr (“heart”) and *dʰeh₁- (“to put, place”).[1][8] Its cognates include Old Irish creitid (“believes”), Welsh credu (“to believe”) and Sanskrit श्रद्दधाति (śraddadhāti, “to trust, believe”).[8][1]

Earliest recorded meaning

The Spanish version of the Cortes of Coyanza, dated 1250 in the CDH, asks the clergy to teach children el credo in Deum, e el pater noster, assi que lo saban de cor “the Credo and the Paternoster, so that they know them by heart”: the prayer, named by its first words.[9] Alfonso X's Estoria de España speaks of the Nicene Creed, el credo in unum deum que cantan ala missa cada fiesta “which they sing at Mass on every feast”.[10]

Semantic evolution

The DCECH and the BDELC date the word only from Saint Teresa in 1565–1566, well after the medieval records.[2][7] Autoridades explained the name: the creed is called so because it begins with this word.[11] Because the prayer is short, it served to measure time: in 1546 a ship stayed afloat no longer than tres credos rezados bien de priesa “three creeds said very fast”, and the Academy recorded en un credo “in a short time” and cada credo “every moment” in 1817;[12][13][5] Portuguese has em um credo “in an instant”.[12][13][5] Con el credo en la boca meant “in fear of danger”.[13]

The secular sense “the beliefs or principles of a person or group” appears in Domínguez's dictionary of 1846 as a political profession of faith, and in Gaspar y Roig as credo político.[14][15] French had the same extension in philosophy in 1771 and in politics in 1794.[6] In Chile Román asked for it to be admitted, noting that politicians used it most;[16][17][3] Alemany recorded it in 1917, and it is now the DLE's second sense.[16][17][3]

Meanings

Noun

  1. (Christianity) The creed: the prayer that states the main articles of the Christian faith; also the part of the Mass in which it is said.[3][20][1]
  2. The set of ideas, principles or convictions of a person or a group: Cada partido defiende su credo.[3][21]

Usage notes

Cada credo “every moment” is now colloquial and obsolete, and con el credo en la boca “in great fear of what may happen” is rare in Spain.[3] In Cuba, Venezuela and Chile con el credo en la boca means “in constant anxiety”.[22]
