Forms

aveia f (plural aveias)[1] Old Galician-Portuguese wrote auea and auena; the 15th century has aueea and avea.[2][3][4] Vieira (1871–1874) still heads the word avêa and calls aveia old.[5]

Etymology

It is inherited from Latin avēna (“oats; straw; shepherd's pipe”), written Old Galician-Portuguese avẽa and Old Galician-Portuguese auea in the oldest texts.[2][6][7][1] The Latin /n/ between vowels was lost, as in coroa, freio and lã, a change typical of Galician-Portuguese against Spanish avena.[8] The learned doublet ⟨avena⟩ “shepherd's pipe” was taken from the Latin word in the 16th century;[6][2] Machado quotes it from Camões.[6][2]

The same Latin word is Galician avea, Italian avena, French avoine (Old French aveine) and Catalan avena.[9][1][10]

De Vaan reconstructs Proto-Italic *aweksnā- and compares Lithuanian aviža, Latvian auzas and Proto-Slavic *ovьsъ “oats”; because the suffixes do not match, he thinks it is probably a word borrowed from a non-Indo-European language.[11][1]

Earliest recorded meaning

A charter of 1271 lists dous moyos millo et auea “two moios of millet and oats”, and one of 1276 has das auenas.[4] Machado's earliest record is later, from a document of 1390 quoted by Viterbo: oito a'avéa, e quatro de milho “eight of oats and four of millet”, among dues paid in grain.[6]

Semantic evolution

In the medieval charters the word names the grain paid in rents and dues.[4][6] The dictionaries describe it as fodder for cattle and fowl that in some places was also made into bread (Caldas Aulete, Silva Bastos), and today as a cereal grown for people and animals, its grain and its flour.[12][13][14] In southern Brazil oat porridge thickened with cornflour was a food for children and the sick.[15] Portuguese dialects also have the shortened form veia.[16]
