Forms

croiseur m (plural croiseurs)[1]

Etymology

It is formed from French croiser + -eur, from the nautical sense of the verb, “to cruise”.[2][3][4][5] That sense is recorded from 1671;[2] the verb itself is from French croix, first meaning “to lay crosswise”.[2][6] The noun goes back to Latin crux, which Picoche thinks was taken from a Mediterranean language, perhaps Punic.[6]

Earliest recorded meaning

Furetière records it in 1690 as a naval term, for a warship sent out cruising.[2][5][7]

Semantic evolution

The word first named any warship cruising on patrol, and it was also used as an adjective (vaisseau croiseur);[7][2] Littré also gives it for the captain of such a ship.[7][2] It then became the name of a class of fast warships that guard sea routes, scout for a fleet and escort convoys, now often armed with missiles.[2][5][8]

In mining it has meant, since Littré in 1863, a vein that cuts across the main vein, also called filon croiseur.[5][7] Littré also records it as a name of the tern, the “sea swallow”.[7]

Timeline

  • 1671 – Croiser is first used as a naval term.[2]
  • 1690 – Furetière records croiseur for a cruising warship.[2][5]
  • 1798 – The Académie's dictionary records the word.[2]
  • 1863 – Littré records the mining sense “cross vein”.[5]

Meanings

Noun

  1. A cruiser, a fast warship used for surveillance, escort and protection at sea.[8][9][2]
  2. Croiseur de bataille, croiseur léger: a battle cruiser, a light cruiser.[2][5]
  3. (mining) A vein that crosses the main vein.[5][7]
  4. (obsolete) The tern.[7]

Adjective

  1. (dated) cruising, of a ship: un bâtiment croiseur.[7][2]

Usage notes

An older croiseur of 1579, a coin worker who marks the coins with a cross, is derived from croix in the sense of the cross stamped on coins, not from the naval verb.[2][10]
