Forms

cerco m (plural cercos)[1] Houaiss records the 15th-century spellings çerco and cerquo.[2]

Etymology

It is a back-formation from Portuguese cercar, as Houaiss, Aurélio, the DLP and Nascentes explain it.[2][3][4][5] Wiktionary calls the derivation from the verb possible.[1] The verb comes from Late Latin circō (“to go round, go about”).[6]

Adolfo Coelho and Meyer-Lübke derived the noun directly from Latin circus (“circle”), as Nascentes reports.[5] Vieira too took it from that word, and gives "the circus of the ancients" as an obsolete sense, and Aurélio enters the old sense "ring, circle" separately, from the same Latin word.[7][3]

Earliest recorded meaning

Houaiss dates the noun to the 13th century from Cunha's index of medieval Portuguese.[2] In the Cantigas de Santa Maria it is a magic circle: cantiga 125 tells how a cleric drew a cerco and conjured up the devils (Como o crerigo fez un cerco e conjurou os diaboos).[8]

Semantic evolution

The sense "siege" is dated by Houaiss and Cunha to the 14th century; the Crónica of 1344 says that the king, because his men could get no food, wanted to raise the siege (quiserasse el rey levantar do cerco).[2][9][8] Cardoso's dictionary of 1569 renders the word by Latin obsidio "siege", and Pereira (1697) refers it to curral, a pen for animals.[10][11]

Morais (1789) lists the siege, the cattle pen, the ring of nets cast round fish, the circus of the ancients, a halo round the moon or sun, and figurative uses such as cerco de misérias.[12] Hunting and fishing kept the ring of beaters closing on game and the circle of nets drawn tight round a shoal; the latter is still recorded in Portugal and Brazil.[13][14] Figuratively the word means a series of events that repeat in order, or insistent pressure on someone.[2][3]

Timeline

  • 1344 – levantar do cerco "to raise the siege" in the Crónica of 1344.[8]
  • c. 1430 – cerco in the Horto do Esposo (copied 1390–1437).[15]
  • 15th century – the spellings çerco and cerquo.[2]
  • 1569 – Cardoso's dictionary renders cerco by Latin obsidio.[10]
