Brute - it ruined eulogy (7)
I believe the answer is:
tribute
'eulogy' is the definition.
(a tribute at a funeral)
'brute it ruined' is the wordplay.
'ruined' indicates anagramming the letters.
'brute'+'it'='bruteit'
'bruteit' is an anagram of 'TRIBUTE'.
(Other definitions for tribute that I've seen before include "Words or gift conveying respect and admiration" , "Something given or said as an expression of esteem" , "Nice words" , "Testimonial, expression of esteem" , "Act of admiration" .)
