Philanthropic volunteers turning to smack? (6,4)
I believe the answer is:
rotary club
'philanthropic volunteers turning to smack?' is the definition.
I can't tell whether this definition defines the answer.
'turning to smack?' is the wordplay.
'turning' becomes 'rotary' (I've seen this in another clue).
'to smack?' becomes 'club' (I am not sure about this - if you are sure you should believe this answer much more).
'rotary'+'club'='ROTARY CLUB'
Can you help me to learn more?
(Other definitions for rotary club that I've seen before include "charitable combination" , "Branch of a worldwide charitable society of professional types" .)
