Pronunciation

  • Brazil: /ˈew/, [ˈeʊ̯][1]
  • Portugal: /ˈew/[1]
  • Northern, Portugal: /ˈjew/[1]
  • Unstressed: [e][1]

Etymology

It is inherited from Late Latin eo (“I”), written Old Galician-Portuguese eu in the oldest texts, the popular form of egō (“I”).[2][1][3][4] Meyer-Lübke considered the shortened form pre-Romance; it occurs in manuscripts of the 6th century, and Nascentes and the scholars he cites date the loss of the /ɡ/ to Vulgar Latin, explaining it by the weak stress of a much-used word.[5] Nunes held that the /ɡ/ fell without trace and the /e/ closed in hiatus.[5]

The same Latin word is Spanish yo, Catalan jo, French je, Italian io and Romanian eu.[6][5] The Latin pronoun goes back to *egō and *h₁eǵ, and is cognate with Ancient Greek ἐγώ (egṓ).[7][1] Houaiss sets beside it the oblique cases of the Latin pronoun, such as the accusative mē, and compares me.[8]

Earliest recorded meaning

Lorenzo antedated Machado's first record of 1265 with eu Eluira Sanchiz “I, Elvira Sanchez” in a document of 1193 and eu Johan Pirit in one of 1242–1252.[9] In the Cancioneiro da Ajuda and the Cantigas de Santa Maria it is the ordinary subject pronoun, used before consonants and vowels alike.[9]

Semantic evolution

The pronoun has kept its form and use since the 13th century.[2][9] Morais (1813) gives its other forms as mim, me and migo.[10] As a noun, o eu “the self, the conscious being” is defined by Figueiredo (1899) and Silva Bastos (1912), and later dictionaries add the ego of psychology.[11][12][8] In nonstandard Brazilian Portuguese eu is also used after prepositions, where the standard language has mim.[1]

The pronoun passed into the Portuguese creoles of Asia: Kristang yo and Macanese io or ieu.[1]

Timeline

  • 13th century – eu in the cantigas and the Cantigas de Santa Maria.[9][8]
  • 1697 – Pereira glosses it with Latin ego.[13]
  • 1813 – Morais lists the forms mim, me and migo.[10]
  • 1899 – Figueiredo defines the noun “the self, consciousness”.[11]
