Forms

crer (first-person singular present creio, first-person singular preterite cri, past participle crido)[1] Old Galician-Portuguese had creer, with the preterite crive, the subjunctives crevesse and crever and the past participles creudo and criudo.[2] The contracted infinitive crer and the present creio (for older creo) appear in the 15th century.[3][4]

Etymology

It is inherited from Latin crēdō (“to believe, to trust”), written Old Galician-Portuguese creer in the oldest texts.[3][4][1][5] Houaiss derives it through a Vulgar Latin infinitive stressed on its second syllable; the two vowels of the old form were later contracted.[3][4]

The same Latin verb is Galician crer, Spanish creer, Catalan creure, French croire, Italian credere and Romanian crede.[1][6]

The Latin verb continues Proto-Italic *krezðō, from Proto-Indo-European *ḱred-dʰeh₁- (“to place one's heart, to trust”), a phrase made of a case form of *ḱḗr (“heart”) and *dʰeh₁- (“to put”).[7][8] Its cognates include Old Irish creitid (“believes”) and Sanskrit श्रद्दधाति (śraddadhāti, “to trust, to believe”).[8][7]

Earliest recorded meaning

The first dated records are in Galician notarial documents: o que eu creo que se Deus quiser in 1270 and o que eu creo que nunca seera “which I believe will never be” in 1274.[2] The Cantigas de Santa Maria have it in the religious sense: log'a judea criya “at once the Jewish woman believed”.[2]

Semantic evolution

The medieval language construed it as creer de (someone) “to believe what someone says” and creer per “to believe by”.[2] Houaiss records as obsolete the pronominal crer-se de “to trust in”.[3] Bluteau defines it as holding something for certain.[9] Aulete adds the intransitive “to have faith”, especially religious faith.[10]

The learned words of the same Latin root came later: crédito in the 15th century and credo, the prayer named from its first Latin word, in 1570.[4] Portuguese also has em um credo “in a moment”.[11]
