Pronunciation

  • Brazil: /ẽˈsaj.u/, [ẽˈsaɪ̯.u], /ĩˈsaj.u/[1]
  • Portugal: /ẽˈsaj.u/[1]

Forms

ensaio m (plural ensaios)[1] The oldest spelling is enssay (13th century); Folqman (1755) still gives ensayo beside ensaio.[2][3][4]

Etymology

It is inherited from Late Latin exagium (“a weighing”).[3][2][1][5] The Latin noun is formed from exigō (“to weigh, measure”), itself from ex- and agō (“to drive”).[1][6] Corominas holds that the Late Latin word, and the Greek word taken from it, already meant “verification”, from which the senses “proof” and “attempt” developed side by side.[7][3] DELPo and Silva Bastos (1912) take the noun instead as a back-formation from ensaiar, but Houaiss and Cunha derive the verb from the noun.[8][9][10][2]

The same Latin word is Galician ensaio, Spanish ensayo, Catalan assaig, French essai and Italian saggio.[11][12] The n of the first syllable has been explained in several ways: by the Portuguese dislike of a bare initial e- (Nunes, followed by Nascentes), by the prefix in- (Menéndez Pidal) or by the analogy of words such as enxame (Cornu).[5][12]

The literary sense “essay” Nascentes takes from English essay, and Aurélio gives it a separate article, from the French word.[5][13] Houaiss treats it as part of the same development of “trial, attempt”.[3]

Earliest recorded meaning

Cunha and Houaiss date the first record, spelt enssay, to the 13th century, with the senses “proof, experiment”.[2][3]

Semantic evolution

Pereira (1697) glosses the word with Latin praeludium and prolusio, a prelude or preliminary exercise.[14] Morais (1789) defines it first as the assay goldsmiths and chemists make of metals, then as any attempt by which someone tests his ability before a greater task, and as a piece of writing in which the mind's powers are tried.[15] Vieira (1871) adds the rehearsal of a part in a play.[16]

Houaiss dates ensaísta “essayist” to 1918, modelled on English essayist.[17] Modern technical senses include materials testing, trial coins and stamp proofs; in Rio Grande do Norte the word names the eve of a vaquejada, and in rugby it is a try.[3][18]
