Forms

onda f (plural ondas)[1] Houaiss records hondas and hõdas in the 14th century and omdas in the 15th.[2]

Etymology

It is inherited from Latin unda (“wave; water in motion”), written Old Galician-Portuguese onda in the oldest texts.[2][3][1][4]

The same Latin word is Galician onda, Spanish onda, Catalan ona, French onde, Italian onda and Romanian undă.[1][5]

De Vaan connects the Latin word with the Indo-European word for water, Proto-Indo-European *ud-ōr, with an oblique stem *ud-n-, the source of Ancient Greek ὕδωρ (húdōr) and of the English word water.[6][7] Wiktionary calls the origin uncertain: perhaps a collective *udn-om (“body of water”), taken as a feminine singular, with the consonants swapped; the likeness of Proto-Germanic *unþī (“wave”) it considers coincidental.[1]

Earliest recorded meaning

Lorenzo's chronology finds the word in the Cantigas de Santa Maria of the 13th century, where Machado had known it only from the 16th: o vento moveu as ondas “the wind stirred the waves”, and a woman who gives birth dentro nas ondas “in the middle of the waves”.[4] A cantiga d'amigo begins Ai ondas que eu vin mirar “O waves that I came to see”.[8]

Semantic evolution

Bluteau (1712–1728) defines the wave as water of the rivers or the sea rising and falling with the wind.[9] Morais (1813) adds the figurative waves of a garment, of curly hair, of silks and marbles, the waves of a flame, and ondas de alvoroços “surges of excitement”.[10] In poetry as ondas is the sea itself.[2][11]

From the surge of water the word passed to any great flow or crowd (uma onda de pessoas), to a sudden feeling, and in physics to a disturbance that travels through a medium.[2][1] Brazilian informal speech gave it the senses “commotion”, “fashion, what is in vogue”, “something great”, “a drug high” and “sham, show”.[2][1]

Timeline

  • 13th century – ondas in the Cantigas de Santa Maria.[4]
  • 14th century – the spellings hondas and hõdas.[2]
  • 1569 – Cardoso glosses onda with Latin fluctus.[12]
  • 1572 – first record of ondeado “wavy”.[3]
  • 1813 – Morais records the figurative waves of hair, silk and feelings.[10]
