I clear up misrepresented characteristic (8)
I believe the answer is:
peculiar
'characteristic' is the definition.
(I've seen this before)
'i clear up misrepresented' is the wordplay.
'misrepresented' is an anagram indicator.
'i'+'clear'+'up'='iclearup'
'iclearup' with letters rearranged gives 'PECULIAR'.
(Other definitions for peculiar that I've seen before include "Odd - individual" , "'Strange, odd (8)'" , "Strange, different from the norm" , "Belonging exclusively to, person or place" , "Out of the ordinary" .)
