Limping (4)
I believe the answer is:
lame
'limping' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lame that I've seen before include "Unable to walk properly" , "Rubbish" , "Hobbling" , "Of excuse, weak and unconvincing" , "Fabric interwoven with metal threads" .)
