Ultimate origin

Etymology

The word for an outlet is borrowed from Latin ēmissārium (“an outlet”), formed from the stem of ēmissus with the suffix -ārium.[2][3]

Earliest recorded meaning

An outlet or channel, chiefly of a lake or reservoir: 1601, in P. Holland's translation of Pliny.[2][3]

Semantic evolution

From 1657 the word was also used in physiology for a canal through which a fluid passes out of the body, a sense last recorded in 1732.[2][3] Johnson (1755) gave this technical sense as "one that emits or sends out", with an example from Arbuthnot on emissaries and absorbent vessels in the skin.[4] The OED marks the outlet sense obsolete except in Roman history,[2][3] and Merriam-Webster Unabridged lists it as archaic.[5]

Timeline

  • 1601 – an outlet or channel, chiefly of a lake.[2][3]
  • 1657 – in physiology, a duct by which a fluid passes out (obsolete by 1732).[2][3]

Meanings

Noun

  1. (archaic) An outlet or channel, especially of a lake, now only in the history of ancient Rome.[5][2][3]
  2. (obsolete, 1657–1732) A duct of the body.[2][3]

First attested

Latin emissarius
Ultimate origin
Latin ēmittō

Etymology

The word for an agent sent on a mission is borrowed from Latin ēmissārius (“sent out; one sent out, a scout, spy”),[2][6][7][8][9] probably through French émissaire, recorded in French in the 17th century.[10][6] The Latin word is formed from ēmissus, the past participle of ēmittō (“to send out”), the source of emit, with the suffix -ārius, English -ary.[2][10][11][7]

Earliest recorded meaning

A person sent on a mission: Barnhart dates it to 1625, when Ben Jonson used it in The Staple of News as the title of the men who gathered the news;[10] the OED quotes the play from its 1631 printing.[2] Merriam-Webster Unabridged gives 1607 as the first date,[5] Dictionary.com 1595–1605[12] and Etymonline the 1620s.[6]

Semantic evolution

The Latin word already meant a scout or spy,[6][9][8] and the English word was at first usually derogatory:[3] it named someone sent to gather information or win adherents for a cause,[2] and after 1663 also simply a spy.[2] Johnson (1755) defined it as "one sent out on private messages; a spy; a secret agent", with examples from Bacon and Swift.[4] The neutral modern sense of an envoy or representative, especially of a government or head of state, is the main one in current dictionaries.[5][13] The adjective, "sent forth", appears in the 17th century,[2] and in anatomy it has described, since 1828, small vessels branching from a main trunk,[2] especially the emissary veins that connect the venous sinuses of the dura mater with veins outside the skull.[5][13]

  • 1828 – adjective, in anatomy, of small vessels branching out.[2]
