The word sleuth as a noun means a detective.   The dictionary also says to look up sleuthhound. As a verb tr. it means to track or follow. Looking up sleuthhound, I see the following:

Word History: Tracking down the history of the word sleuth requires a bit of etymological sleuthing. The immediate ancestor of our word is the compound sleuthhound, a dog, such as a bloodhound, used for tracking or pursuing. This term took on a figurative sense, tracker, pursuer, which is closely related to the sense detective.  From sleuthhound came the shortened form sleuth, recorded in the sense detective as early as 1872. The first part of the term sleuthhound means track, path, trail, and is first recorded in a Middle English work written probably around 1200. The Middle English word, which had the form sloth, with eu representing the Scots development of the Middle English ( ), was a borrowing of the Old Norse word sl dh, a track or trail. 

That’s a little more than you wanted to know, right?

Well I am also your Winesleuth. I try to find wines that are not out of reach for the average person so that we can all enjoy wine together and make the word a better place.

I’m sleepy.   I had a glass or two of cab tonight and I am going to go for now.
