Repeated ceremony outside front of embassy highly thought of (10)
I believe the answer is:
reiterated
'repeated' is the definition.
('reiterate' can be a synonym of 'repeat')
'ceremony outside front of embassy highly thought of' is the wordplay.
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'outside' means one lot of letters goes inside another.
'front of' suggests taking the first letters.
'highly thought of' becomes 'rated' (I've seen this before).
The initial letter of 'embassy' is 'e'.
'rite' enclosing 'e' is 'reite'.
'reite'+'rated'='REITERATED'
(Another definition for reiterated that I've seen is " Said (something) again".)
