incognito[1]

Etymology

It is borrowed from Italian incognito (“unknown”), recorded in Italian from Dante (1317–1321).[2][3][4][5] The Italian word is from Latin incognitus (“unknown, not examined”),[2][3] formed from in- (“not”) and cognitus (“known”), the past participle of cognōscō (“to get to know”),[6][7] the verb that gave connaître.[2][3]

Earliest recorded meaning

It is first recorded in 1581, in the Négociations du Levant, as an adverb: a Muscovite had lately passed through the town incognito on his way to see the Pope.[2][3]

Semantic evolution

The adverb was used first of princes and great persons who travelled without revealing their identity, so as to escape the rules of protocol;[2][8] the Académie defined it so in 1694, adding that it could be said of anyone who did not wish to be known.[9] By extension it meant “without the thing being known” (1690, Boursault), a sense now out of use.[3][7]

From the 18th century (before 1750) l'incognito became a noun for the situation of a person who hides their identity, as in garder l'incognito.[3][10]

Timeline

  • 1317–1321 – Italian incognito “unknown” is recorded in Dante.[2][3]
  • 1581 – First recorded in French, as an adverb.[2][3][4]
  • 1690 – Boursault uses it for “without the thing being known”.[3][7]
  • 1694 – The Académie's dictionary records the adverb.[9]
  • Before 1750 – L'incognito is used as a noun.[3]

Meanings

Adverb

  1. Without making oneself known, under a false name or without the marks of one's rank: le ministre est venu incognito.[10][2][11]
  2. (obsolete) Without the thing being known, secretly.[3][7]

Adjective

  1. Unknown, anonymous.[12][1]

Noun

  1. The state of a person who hides their identity, anonymity: garder l'incognito.[10][11][13]

Usage notes

As an adverb incognito is invariable, but as a noun it takes a plural -s.[11][1] Littré recommended the Italian pronunciation with /ɲ/ and found the pronunciation with a hard /g/ less good.[8]
