Forms

agente m or f by sense (plural agentes)[1] The 15th century also writes agete.[2]

Etymology

It is borrowed from Latin agēns (“doing, acting”), the present participle of agō (“to drive, do”).[2][3][4][1] Nascentes calls it a learned word.[5] Wiktionary adds that it can now be analysed as agir with the suffix -ente.[1]

As a noun, the Latin participle meant “pleader, advocate”, and Medieval Latin used it for the agent of a lord or a church and for a royal officer.[6][7] The verb goes back to Proto-Indo-European *h₂eǵ- (“to drive”), and is cognate with Ancient Greek ἄγω (ágō, “to lead”).[1][8]

Earliest recorded meaning

Houaiss and Cunha date the word to the 15th century, from Cunha's index of medieval Portuguese, spelt agente and agete.[2][3]

Semantic evolution

Bluteau (1712–1728) treats agente first as a term of physics, whatever has the power to produce an effect, with the agente natural and the agente livre; he then gives the agent of a prince, a minister who acts without the title of ambassador, and the agent of a body such as the University of Coimbra.[9] Feijó (1734) defines it simply as one who handles business.[10] Morais has it as an adjective “active” in 1789, and as a noun in 1813: any active cause, the motive power in mechanics, a prince's minister at a foreign court, and the proxy of a corporation.[11][12] The grammatical sense, the doer of the action, and the agent of a passive verb were in the dictionaries by Figueiredo's time.[13] The modern senses of spy, police officer and offender are listed by Houaiss.[2]

Timeline

  • 15th century – first records, spelt agente and agete.[2][3]
  • 1607 – agente in a private letter.[14]
  • 1712–1728 – Bluteau gives the physical, diplomatic and administrative senses.[9]
  • 1734 – Feijó: one who handles business.[10]
  • 1789 – Morais enters the adjective “active”.[11]
  • 1813 – Morais enters the noun with its causal, mechanical and diplomatic senses.[12]
  • 1871–1874 – Vieira derives it from Latin agens.[15]
