Object of wild rage during a race (6)
I believe the answer is:
target
'object' is the definition.
(synonyms)
'wild rage during a race' is the wordplay.
'wild' indicates an anagram.
'during' is an insertion indicator.
'a race' becomes 'tt' ().
'rage' is an anagram of 'arge'.
'arge' going into 'tt' is 'TARGET'.
'of' acts as a link.
(Other definitions for target that I've seen before include "Something to aim for" , "purpose" , "Objective, mark" , "Point to aim at (6)." , "Select for attack" .)
