Stony he may be, but can still manage a cigar (5)
I believe the answer is:
craig
'stony he may be but can still' is the definition.
The definition suggests a singular noun which matches the answer.
'manage a cigar' is the wordplay.
'manage' is an anagram indicator (I've seen this in other clues).
'cigar' is an anagram of 'CRAIG'.
Can you help me to learn more?
(Other definitions for craig that I've seen before include "Scottish boy" , "Fellow" , "Daniel --, actor" .)
