Honour suffering of European veteran (8)
I believe the answer is:
venerate
'honour' is the definition.
(I know that honour is a more specific form of the action the venerate)
'suffering of european veteran' is the wordplay.
'suffering of' indicates an anagram.
'european' becomes 'e' (abbreviation e.g. EU).
'e'+'veteran'='eveteran'
'eveteran' anagrammed gives 'VENERATE'.
(Other definitions for venerate that I've seen before include "Regard (something) with great respect" , "Regard with reverence" , "Think a great deal of" , "Revere highly" , "Treat with respect" .)
