Etymology

The word for the field is inherited from Latin ager (“field, piece of land”), written Old Galician-Portuguese agro in the oldest texts.[1][5][3] Wiktionary gives it as a learned borrowing from the Latin word, or else from the Old Galician-Portuguese noun.[4]

Spanish agro is a learned word, first recorded in 1645;[6] Corominas notes that it became a popular word in Galicia.[6] The REW gives Romanian agru as an inherited outcome of the Latin word.[7]

The Latin noun goes back to Proto-Italic *agros and Proto-Indo-European *h₂éǵros (“uncultivated field, pasture”).[8][4] It is cognate with Ancient Greek ἀγρός (agrós) and Old English æcer.[4]

Earliest recorded meaning

A Latin charter of 906 already has the Romance noun beside its plural, inter agra argirizi et agro ubi … habitat “between the fields of Argirizi and the field where … lives”.[9] Machado records it in the Inquirições of 1258, in a list where Agra is also a place name.[5] In Galician-Portuguese charters it appears in 1259 as un agro que jaz “a field that lies …”, and in 1272 as agrro.[9] One of the Cantigas de Santa Maria has se ora podesses yr / ao agro a teu amo “if you could now go to the field to your master”.[9][2] Houaiss dates the word to the 13th century.[1]

Semantic evolution

The medieval word meant an enclosed piece of farmland, usually a single property.[10][9] Bluteau (1712–1728) still defined it as fruitful land, with quotations from the Monarquia Lusitana and Rodrigues Lobo, and Morais (1789) as arable land, with agro do Senhor Deos from Barros.[11][12] The old Caldas Aulete explains this figure, o agro do Senhor, as the souls to be cultivated for religion.[13]

Aurélio and Houaiss mark the noun as archaic, but the DLP records a regional use in the Alentejo for the yield of the crops and livestock of an estate.[14][1][15] The word lives on in many place names.[5]

Forms

agro (feminine agra, masculine plural agros, feminine plural agras)[4]

Etymology

The word for “sour” is inherited from Vulgar Latin ācrus (“sharp, sour”), the classical adjective Latin ācer (“sharp, pungent”) moved from the third declension to the second.[1][2][4] The Appendix Probi already condemns the accusative of the Vulgar Latin form.[16][17]

The same Vulgar Latin form gave Romanian acru, Italian agro, French aigre, Catalan agre and Old Spanish agro.[18] The Old Spanish word was replaced by Spanish agrio, altered under the influence of the verb agriar; the older form is first recorded in 1251.[19][20] Galician uses agre.[21]

The Latin adjective comes from Proto-Italic *akris and Proto-Indo-European *h₂eḱrós (“sharp”), and is cognate with Ancient Greek ἄκρος (ákros, “highest, outermost”).[8][4]

Earliest recorded meaning

The first record that Lorenzo's chronology gives is the chronicle of 1344, as arvores que som agras “the trees that are sour”.[9] Houaiss dates the adjective to the same year, and Cunha to the 14th century.[1][2]

Semantic evolution

From the taste of unripe fruit the word passed to anything harsh: Morais (1813) gives the figurative senses “unpleasant, hard to bear” and montes, caminhos agros “rugged mountains and paths, hard to climb”.[22] Vieira lists “steep, rough, arduous, rigorous” as figurative senses in 1871.[23] Bluteau quotes the proverb O gosto danado julga o doce por agro “a spoilt palate takes the sweet for sour”.[11]

Used as a noun it means sourness, and figuratively grief or bitterness; in popular speech in Portugal it is also the part of a fruit near the stalk, which gets less sun and stays less sweet.[15][24] Medieval Portuguese already formed agraço (first as agraz, the juice of unripe grapes) and agrura from it.[2][25][26]

Timeline

  • 13th century – agraz “verjuice”, the oldest derivative.[2][25]
  • 1344 – as arvores que som agras in a chronicle.[9][1]
  • c. 1430 – agro in the Horto do Esposo.[27]
  • 15th century – first record of agrura.[26]
  • 16th century – first record of agrodoce.[2]
  • 1813 – Morais records the figurative senses “harsh” and “rugged”.[22]

Meanings
