Note current clergyman is a member of the board (8)
I believe the answer is:
director
'a member of the board' is the definition.
(as in a board of directors)
'note current clergyman' is the wordplay.
'note' becomes 'd' (musical note).
'current' becomes 'I' (symbol for electric current).
'clergyman' becomes 'rector' (rector is a kind of clergyman).
'd'+'i'+'rector'='DIRECTOR'
'is' is the link.
(Other definitions for director that I've seen before include "leader" , "This person could be on board or in theatre" , "Controller of production or member of a board" , "Big cheese" , "Boss posing as creditor" .)
