‘Exciting dream revolutionary had creates political initiative (8)
I believe the answer is:
demarche
'political initiative' is the definition.
(I've seen this before)
''exciting dream revolutionary' is the wordplay.
''exciting' indicates an anagram.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'dream' with letters rearranged gives 'demar'.
'demar'+'che'='DEMARCHE'
'had creates' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for demarche that I've seen before include "political step" , "Mad cheer for diplomatic manoeuvre" , "A diplomatic initiative" , "A move or countermove in diplomatic relations" , "Manoeuvre in diplomatic relations, from French" .)
