hustler

I'm a little stuck... Click here to teach me more about this clue!

'cheat' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?

'luther's terrible' is the wordplay.
'terrible' indicates anagramming the letters.
'luthers' anagrammed gives 'HUSTLER'.

Can you help me to learn more?

(Other definitions for hustler that I've seen before include "Prostitute" , "Aggressive seller" , "Illicit dealer (mainly US)" , "Energetic or crooked operator" , "Aggressive dealer" .)
