Etymology

The word for the fish is inherited from Latin raia (“ray, skate”), spelt Old Galician-Portuguese raya in the 13th century.[2][1][3][4][5] Its variant arraia is recorded from 1367.[6] Houaiss explains its ⟨a-⟩ as prosthetic, perhaps the feminine article run together with the noun.[2][6]

The same Latin word is Spanish raya, Italian razza (from Venetian) and French raie.[7][8] The French word was taken from Latin in the 12th century.[9]

The OLD calls the Latin word of unknown origin.[10] De Vaan reads it as /rajja/, from Proto-Italic *rajjā or *ragjā, and compares Middle Dutch rogghe and Old English reohhe, words for the ray in Middle Dutch and Old English; whether the English words can go back to the same form is disputed.[11]

Semantic evolution

Cardoso's Latin–Portuguese dictionary of 1562 renders the Latin raia by a raya, and his Portuguese–Latin one of 1569 gives raia for the fish.[12][13] In Brazil the word is also a kite, the toy.[2] Houaiss explains the name by the likeness to these fishes with their long thin tail, as Câmara Cascudo pointed out.[2] The kite sense is recorded in Alagoas and Pernambuco.[14]

Forms

raia f (plural raias)[1]

Etymology

The word for a line or border is, for Houaiss and Cunha, a feminine formed from Portuguese raio (“ray; spoke”) + -a.[2][15][1] The masculine noun is from Latin radius (“staff; spoke of a wheel; ray of light”).[16][15] Nascentes, Aurélio and Michaelis derive the noun instead from Vulgar Latin *radia, formed on the Latin word because spokes and rays are straight lines.[3][5][17] Wiktionary weighs both and calls the origin uncertain, and the DLP says only that it perhaps comes from the Latin word.[1][4] Houaiss records the form arraia with a prosthetic ⟨a-⟩ in the 15th century.[6]

The same word is Galician raia.[18] For Spanish raya “line”, which Corominas and Pascual find from 1288, they suggest the same origin, while the DLE derives it from Late Latin radia.[19][20] De Vaan finds no clear etymology for the Latin word and thinks it unlikely to be related to rādīx (“root”).[21]

Earliest recorded meaning

A cantiga d'amigo, undated in the glossaries, already uses raia for the first light of the sun: quando saía la raia / do sol nas ribas do Sar “when the sun's first ray came out on the banks of the Sar”.[22][23] In prose the word is first recorded in the 15th century as araya “frontier”, and as raia in 1567, in the sense “line of demarcation”.[6][2]

Semantic evolution

Houaiss dates the sense “stroke, line” to the 17th century.[2] Morais (1789) gives the lines of the hand, the lines drawn in ink or chalk for some games, a boundary or frontier, and figuratively the limits of something.[24] The adjective raiano “of the border” is first recorded in Aulete's dictionary of 1881.[25]

Modern technical senses include the grooves of a rifled barrel, the lanes of a swimming pool and the dark lines of the solar spectrum.[2][5] In Brazil it is a straight racecourse for horses, especially in the south, where fugir da raia means to dodge a fight.[26][27][2] Popular speech in Portugal uses it for a blunder.[4][1]

Timeline

  • 15th century – the prosthetic form araya “frontier”.[6]
  • 1567 – raia “line of demarcation”.[2]
  • 1594–c. 1595 – the spelling raya.[2]
  • 17th century – first record of the sense “stroke, line”.[2]
  • 1789 – Morais lists the lines of the hand, game lines, a frontier.[24]
  • 1881 – raiano is first recorded in Aulete's dictionary.[25]

Michaelis puts the kite sense, which it records in Minas Gerais and the North-East, under the word for the line rather than under the fish.[17]
