Words of praise for butter I spread (7)
I believe the answer is:
tribute
'words of praise' is the definition.
(tribute can mean words in praise of someone)
'butter i spread' is the wordplay.
'spread' indicates an anagram.
'butter'+'i'='butteri'
'butteri' is an anagram of 'TRIBUTE'.
'for' acts as a link.
(Other definitions for tribute that I've seen before include "Compliment" , "Expression of praise" , "Act of admiration" , "Payment to overlord" , "Honour" .)
