Walk unevenly (4)
I believe the answer is:
limp
'walk unevenly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for limp that I've seen before include "Flaccid" , "Uneven manner of walking" , "Walk with an uneven stop" , "Slack, wilted" , "Hanging loosely - hobble" .)
