Etymology: a shortened form of sleuthhound "a dog that follows a track or trail by scent," from Middle English sleuth "a track or trail"; of Norse origin : 2DETECTIVE Word History In Middle English the word sleuth meant "the track or trail left by an animal or person." After the 15th century sleuth was seldom used except in such words as sleuth-dog and sleuthhound. These were terms for a dog trained to follow a track or trail. The sleuthhound became well known for its eager and thorough pursuit of an object. Later the word sleuthhound came to be used for a "detective." The modern word sleuth first came into use as a shortened form of sleuthhound.
