IPA: //ˈsluːθhaʊnd//
KK: /ˈsluːθhaʊnd/
A type of dog that is trained to track scents, often used in hunting or police work, or a person who investigates and solves mysteries.
The sleuthhound followed the scent trail through the forest, leading the detectives to the missing person.
Sleuthhound is formed from "sleuth" (from Old English *slūþ, meaning to track or trail) and "hound" (from Old English *hund, meaning dog). The word refers to a dog that is used for tracking or hunting, particularly in the context of following a scent.
Think of a dog that is skilled at 'tracking' ('sleuth') and is a 'hound' — that's why a sleuthhound is a dog that tracks scents.
