The king worried before Germany is given an honour (8)
I believe the answer is:
knighted
'given an honour' is the definition.
(I've seen this before)
'the king worried before germany' is the wordplay.
'worried' is an anagram indicator.
'before' says to put letters next to each other.
'germany' becomes 'd' (international vehicle registration code).
'the'+'king'='theking'
'theking' is an anagram of 'knighte'.
'knighte'+'d'='KNIGHTED'
'is' acts as a link.
(Other definitions for knighted that I've seen before include "Dubbed 'Sir'" , "Given an honour" , "Made a Sir" , "Given a title" .)
