Forms

ator m (plural atores, feminine atriz, feminine plural atrizes)[1] The first records are spelt actor, the spelling of Portugal before the 1990 agreement.[2][3][1] The feminine is atriz, recorded from the 18th century.[3]

Etymology

It is borrowed from Latin āctor (“one who drives or does; agent; plaintiff; performer”).[2][3][4] Nascentes calls it semi-learned, and Wiktionary has it from Old Galician-Portuguese abtor, a semi-learned form.[5][1]

The Latin word is an agent noun of agō (“to drive; to do”) with -tor.[6][1] Machado notes that the old Portuguese meaning was only legal, “plaintiff”, and thinks the theatrical sense owes something to French, where French acteur came to belong to the stage alone.[4]

Earliest recorded meaning

Houaiss's first record is of 1532.[2] Machado quotes the legal sense from the Ordenações Manuelinas: Actor que demanda em juízo mais do que lhe é devido é condenado nas custas em tresdobro “a plaintiff who claims in court more than he is owed is sentenced to pay the costs three times over”.[4]

Semantic evolution

Barbosa's dictionary of 1611 has both senses, actor nas demandas “in lawsuits” and actor nas comoedias “in comedies”.[4] Cunha dates the theatrical sense to the 17th century.[3] Morais (1813) defines the word as a performer of drama and marks “plaintiff” as out of use.[7] Today the word also means anyone who plays an active part in an event, and, figuratively, a dissembler.[2][8]

Timeline

  • 1532 – first record, spelt actor.[2]
  • 1611 – Barbosa gives the legal and the theatrical sense.[4]
  • 17th century – Cunha's date for the sense “stage actor”.[3]
  • 18th century – first record of the feminine atriz.[3]
  • 1813 – Morais marks the legal sense as obsolete.[7]

Meanings

Noun

  1. An actor, one who plays a part in plays, films or television series: O ator estreou no teatro aos vinte anos.[2][1]
  2. Someone who takes an active part in an event: um dos atores da independência.[2][8]
  3. (figurative) Someone good at pretending; a hypocrite.[2][9]
  4. (law, obsolete) A plaintiff.[9][7]
