Take for granted parking and carry on (7)
I believe the answer is:
presume
'take for granted' is the definition.
(thesaurus)
'parking and carry on' is the wordplay.
'parking' becomes 'p'.
'and' is a charade indicator (letters next to each other).
'carry on' becomes 'resume' (I've seen this before).
'p'+'resume'='PRESUME'
(Other definitions for presume that I've seen before include "Believe" , "Surmise" , "Take to be the case" , "Take for granted" , "Suppose without proof" .)
