Pronunciation

  • UK: /pɹəˈd͡ʒɛktə/[1]
  • US: /pɹəˈd͡ʒɛktɚ/[1]

Etymology

It is formed from English project + -or,[2][3][4][5] partly after Medieval Latin projector (“one who throws, one who throws away”), recorded in British sources from before 1215,[3] from prōiciō (“to throw forth”).[3] Etymonline calls it an agent noun in Latin form from the verb.[6] The verb project is from Late Latin prōiectō (“to thrust forward”), from prōiectus, the past participle of prōiciō, which is formed from prō- (“forward”) and iaciō (“to throw”).[6]

Earliest recorded meaning

A person who forms a project or plans an enterprise: 1596, in a letter of the Earl of Essex.[3][4][6]

Semantic evolution

The planner soon became a schemer: from 1615 the word was used of a promoter of unsound ventures or a swindler,[3] and Johnson (1755) gave "one who forms wild impracticable schemes" as its second sense.[7] That use is now archaic.[3][2] From 1674 the word also meant a person or thing that throws something forward, later a device for firing projectiles.[3] From 1832 it also meant a forecaster.[3] The modern technical senses began with an apparatus throwing a strong beam of light (1860)[3] and an apparatus throwing an enlarged image onto a screen, first recorded before 1884;[3] Etymonline dates the image sense to 1884.[6]
