sleuth: [12] Sleuth originally meant ‘track, trail’ (‘John of Lorn perceived the hound had lost the sleuth’, John Barbour, The Bruce 1375). It was borrowed from Old Norse slóth ‘track, trail’, which was probably also the ultimate source of English slot ‘trail of an animal’ [16]. In the 14th century the compound sleuth-hound ‘bloodhound for tracking fugitives’ was coined. This was later shortened back to sleuth, and applied in 19th-century America to a ‘detective’. => slot
sleuth (n.)
c. 1200, "track or trail of a person," from Old Norse sloð "trail," of uncertain origin. Meaning "detective" is 1872, shortening of sleuth-hound "keen investigator" (1849), a figurative use of a word that dates back to late 14c. meaning a kind of bloodhound. The verb (intransitive) meaning "to act as a detective, investigate" is recorded from 1905. Related: Sleuthed; sleuthing.
