From the same root
Forms
pai m (plural pais)[1] Old Galician-Portuguese wrote pai and pay, and the 15th century paay and pae.[2][3] Bluteau in 1712 still gives pay and pae beside pai.[4]
Etymology
It is inherited from Latin pater (“father”), written Old Galician-Portuguese pay in the oldest texts.[2][3][1] Houaiss and Cunha explain it as a reduction of the regular outcome Old Galician-Portuguese padre to *pade and pae, probably under the influence of children's speech, which also shows in the reduplicated papá of Portugal and papai of Brazil.[2][3][5] Meyer-Lübke calls the Portuguese form a pet name.[6] Nascentes reports other views: Diez saw the loss of a final -r, and Cornu compared the change with that of Pedro to Pero.[7] Wiktionary compares the similar reduction of mãe from Latin māter.[1] The full form padre survives as a doublet, but lost the sense “father” in the 15th and 16th centuries.[7][1]
The same Latin word is Galician pai, Mirandese pai, Spanish padre, Catalan pare, Occitan paire, French père and Italian padre.[6][1] The Latin noun goes back to Proto-Indo-European *ph₂tḗr (“father”).[8][1] De Vaan reports that its root is disputed: it may be a derivative of a root “to protect”, or a formation with an agent suffix from a nursery word.[8]
Earliest recorded meaning
The word is recorded from the 13th century.[2][3] In a cantiga of Johan Soairez Somesso it is already one syllable, rhyming with vai, and a satirical cantiga of the same poet says of Dona Orraca Abril per como a quer casar seu pai “the way her father wants to marry her off”.[9] The sense is “father”, the man who begot a child.[2][9]
Semantic evolution
Bluteau in 1712 enters pai, pay and pae, and gives the theological sense of God the Father, the first person of the Trinity, beside Adam as “our first father” and the title once given to the pagan gods.[4] Figurative senses followed: the founder or creator of something, a benefactor or protector, and in the plural the parents or the ancestors.[2][10][11][1] In Brazil the word was also used for a native chief.[12][13] Compounds include pai de santo, a priest of the Afro-Brazilian religions, and pai natal, Father Christmas.[1]
The word passed into the Portuguese-based creoles (Kabuverdianu, Guinea-Bissau Creole and Kristang pai, Sãotomense pe), into Ambonese Malay and into Old Tupi as paîa.[1]
