Etymology

It is the agent noun from Latin dētegō (“to uncover, reveal”), with the suffix -tor.[4][1][5] The verb is formed from dē- and tegō (“to cover”),[6] which goes back to Proto-Italic *teg-e/o- and Proto-Indo-European *(s)teg-e/o- (“to cover”).[7]

Earliest recorded meaning

Tertullian is the first to use it, figuratively, in his work against Marcion, where Christ is the “detector creatoris”, the one who reveals the creator.[4][8][3]

Semantic evolution

In Late Latin it meant one who uncovers or reveals, mostly in Christian writers;[8][4] a scholiast on Statius also uses it.[4] In the Visigothic laws it is an informer who discloses a crime,[9][3] and British medieval sources use it in the same sense.[10]

English borrowed it in the 1540s for one who detects; the sense of a device dates from 1833.[5]

Timeline

  • c. 160–220 AD – Tertullian calls Christ the revealer of the creator.[4][3]
  • 7th century – The Visigothic laws use it of an informer who discloses a crime.[9][3]
  • 14th century – A Scottish church statute gives half of a fine to the informer.[10]
  • 1540s – English borrows it as detector, one who detects.[5]
