Approve of or object to a wild rose (7)
I believe the answer is:
endorse
'approve of' is the definition.
(I've seen this in another clue)
'object to a wild rose' is the wordplay.
'object' becomes 'end' (I've seen this in other clues).
'to a wild' indicates an anagram.
'rose' anagrammed gives 'orse'.
'end'+'orse'='ENDORSE'
'or' is the link.
(Other definitions for endorse that I've seen before include "Champion" , "Give public approval of (something)" , "Approve of, sign on back as of cheque" , "Back, support" , "Put penalty points on (a driving licence)" .)
