Forms

spéculateur m (plural spéculateurs, feminine spéculatrice)[1]

Etymology

It is borrowed from Latin speculātor (“observer, spy, messenger, guard”),[2][3][4] the agent noun of speculor (“to observe, watch”).[4][5] Littré traces the verb to speculum (“mirror”) and speciō (“to see”).[5] The financial sense came from that of a theorist, by applying the idea of reflection to dealings on the stock market,[2] under the influence of spéculation;[3][6] the Robert dictionaries therefore describe the modern word as formed on the stem of that noun after the Latin one.[7][6]

Earliest recorded meaning

It is first recorded in 1355, in Pierre Bersuire's translation of Livy, in the sense of a sentry or lookout.[2][3]

Semantic evolution

From the Latin word the French one took the senses “observer of the heavens” (1532) and “observer” in general (1549), a sense still alive in the classical period, and briefly that of an inspector (1556).[3][2] In Middle French it also meant “executioner” (1375, 1541), through confusion of the Latin word with Late Latin spiculator.[3] La Fontaine used it of an astrologer who fell into a well while watching the stars (1668).[4][7] Littré still lists a military use for a sentinel or scout in 18th-century writers.[5]

From 1607 it meant a person given to theoretical reflection, and later (1654) a theorist as opposed to a practitioner.[3][2] In 1745 it took the financial sense of a person who speculates on the market, which has since replaced all the others.[3][2][6] Balzac used the feminine spéculatrice as an adjective meaning “calculating, self-interested” in 1839.[2][8]
