Not pitying crooked hustlers (8)
I believe the answer is:
ruthless
'not pitying' is the definition.
The definition and answer are not the same part of speech.
'crooked hustlers' is the wordplay.
'crooked' indicates anagramming the letters (a crooked or disrupted version of the letters).
'hustlers' anagrammed gives 'RUTHLESS'.
Can you help me to learn more?
(Other definitions for ruthless that I've seen before include "hard" , "Hustlers can be without mercy" , "Callous" , "Brutal" , "Showing no compassion" .)
