    The detective kept them in view. He made his way casually along the inside of the shelter until he reached an open scuttle close to where the two men were standing talking.

    […] Sherlock Holmes remarked calmly. […] "Well, I have a trade of my own. I suppose I am the only one in the world. I'm a consulting detective, if you can understand what that is. Here in London we have lots of Government detectives and lots of private ones. When these fellows are at fault they come to me, and I manage to put them on the right scent. They lay all the evidence before me, and I am generally able, by the help of my knowledge of the history of crime, to set them straight. There is a strong family resemblance about misdeeds, and if you have all the details of a thousand at your finger ends, it is odd if you can't unravel the thousand and first.[…]"

    1887, A[rthur] Conan Doyle, “A Study in Scarlet”, in Beeton’s Christmas Annual, London; New York, N.Y.: Ward, Lock & Co., part I (Being a reprint from the reminiscences of John H. Watson, M.D., […]), chapter II (The Science of Deduction), pages 12–13

    Had they responded this way in France or America, this wouldn't have surprised me, but wasn't everyone in England supposed to be a detective? Wasn't every crime, no matter how complex, solved in a timely fashion by either a professional or a hobbyist? That's the impression you get from British books and TV shows. Sherlock Holmes, Miss Marple, Hetty Wainthropp, Inspector George Gently: they come from every class and corner of the country. There’s even Edith Pargeter's Brother Cadfael, a Benedictine monk who solved crimes in twelfth-century Shrewsbury. No surveillance cameras, no fingerprints, not even a telephone, and still he cracked every case that came his way.

    Synonyms: private detective, private investigator, sleuth, bloodhound, Dick Tracy, Hercule Poirot, Jessica Fletcher, Miss Marple

    Unfortunately for classics in England, the time when Erasmus and his mates got detectiving and sorted out more or less how classical Greek and Latin had been pronounced just preceded the great Vowel Shift in English, so when all the English long vowels made their exciting trek round the mouth they took the fresh new Latin ones with them for the ride.

Origin

  1. Russianдетекти́в
  2. Dutchdetective
  3. Classical Latindētēct-
  4. Englishdetective

The adjective is from Classical Latin dētēct-, past participial stem of dētegō (“to detect”), + -ive. By surface analysis, detect + -ive. Noun sense 1 is an ellipsis of detective policeman, detective officer, or a similar construction. The later more general noun sense 2 was derived by extension. The verb is also from the noun. Noun sense 3 (“a work of detective fiction”) is a semantic loan from Dutch detective and Russian детекти́в (detektív), both from English.
