Government's current input to local pit conversion (9)
I believe the answer is:
political
'government's' is the definition.
(I know this)
'current input to local pit conversion' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'input to' is an insertion indicator.
'conversion' is an anagram indicator.
'local'+'pit'='localpit'
'localpit' anagrammed gives 'poltical'.
'i' placed within 'poltical' is 'POLITICAL'.
(Other definitions for political that I've seen before include "Governmental" , "Involved with affairs of state" , "for parties?" .)
