Diplomatic manoeuvre reached beginning of mutual arrangement (8)
I believe the answer is:
demarche
'diplomatic manoeuvre' is the definition.
'demarche' can be an answer for 'manoeuvre' (thesaurus). I am unsure of the 'diplomatic' bit.
'reached beginning of mutual arrangement' is the wordplay.
'beginning of' says to take the initial letters.
'arrangement' is an anagram indicator.
The initial letter of 'mutual' is 'm'.
'reached'+'m'='reachedm'
'reachedm' is an anagram of 'DEMARCHE'.
Can you help me to learn more?
(Other definitions for demarche that I've seen before include "A move or countermove in diplomatic relations" , "political step" , "Manoeuvre in diplomatic relations, from French" , "A political initiative" , "A diplomatic initiative" .)
