Forms
deus m (plural deuses, feminine deusa or (poetic) deia, feminine plural deusas or (poetic) deias)[1] Old Galician-Portuguese wrote Deus; the Cancioneiro da Ajuda never has deos, which Houaiss dates from the 14th century.[2][3] Old Portuguese also had a form des.[4] Morais (1813) held that etymology and pronunciation called for Deus but entered the word under Deos because of usage.[5]
Etymology
It is inherited from Latin deus (“god”), written Old Galician-Portuguese deus in the oldest texts.[3][6][1] Houaiss calls it a semi-learned word, kept close to the Latin by the Church.[3] Unusually, it continues the Latin nominative rather than the accusative deum.[1] Early Spanish kept both forms, until Spanish dios prevailed over Old Spanish dio through its use in prayers and exclamations.[7]
The same Latin word is Galician deus, Catalan déu, French dieu, Italian dio and Romanian zeu.[4][1]
The Latin noun comes from deivos, found in the Duenos inscription, from Proto-Italic *deiwos and Proto-Indo-European *deywós (“god”), a derivative of *dyew- (“sky, heaven”).[1][8] De Vaan glosses the Indo-European word “god, divinity (god of the clear sky)”; its cognates include Lithuanian diẽvas and Old Irish dia.[8][9] The Latin dīvus, diēs and Iuppiter come from the same root.[1]
Earliest recorded meaning
The 13th-century cantigas use the word constantly in invocations and oaths: par Deus “by God”, por Deus, se Deus quiser “God willing”, ai Deus.[2] The Cantigas de Santa Maria also use it for a pagan god (algun deus).[2]
Semantic evolution
The Christian God and the gods of other religions have been named by the word since the Middle Ages; the modern dictionaries add figurative senses, a person or thing that is idolised, and the philosophers' first principle.[2][3][10] The feminine is deusa, with a poetic deia recorded from 1572.[1][6]
In Japan the Christian God was called デウス (Deusu).[1] Javanese formed dejos from it in the 16th century; through Chinese Pidgin English this became the English joss “Chinese idol”, recorded in 1711.[11][1]
