Go slowly, looking tired (4)
I believe the answer is:
limp
'tired' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for limp that I've seen before include "exhausted" , "Walk with an uneven stop" , "loose" , "Hanging loosely - hobble" , "Wanting stiffness" .)
