Shaming partner of leading man dismissing deal (6)
I believe the answer is:
naming
'shaming partner' is the definition.
I can't judge whether this definition defines the answer.
'leading man dismissing deal' is the wordplay.
'leading' means one lot of letters go next to another.
'dismissing' indicates an anagram (I've seen 'dismissed' mean this).
'deal' becomes 'ing' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'man' anagrammed gives 'nam'.
'nam'+'ing' is 'NAMING'.
'of' is the link.
Can you help me to learn more?
(Other definitions for naming that I've seen before include "Conferring appellation on" , "Identifying; mentioning" , "Calling" , "Titling" , "Christening" .)
