Lame man rights wrong (9)
I believe the answer is:
hamstring
'lame' is the definition.
(hamstringing is a kind of laming)
'man rights wrong' is the wordplay.
'wrong' indicates an anagram.
'man'+'rights'='manrights'
'manrights' is an anagram of 'HAMSTRING'.
(Other definitions for hamstring that I've seen before include "Tendon at back of knee" , "hamper" , "Cramp the style of" , "Impede" , "Thwart, severely restrict" .)
