Limped excessively carrying hamper (6)
I believe the answer is:
impede
'hamper' is the definition.
(I've seen this before)
'limped excessively carrying' is the wordplay.
'carrying' indicates the answer is hidden within the clue.
'IMPEDE' is hidden within 'limped excessively'.
(Other definitions for impede that I've seen before include "Hinder or obstruct, say progress" , "Hinder, be obstructive" , "Delay, be an obstacle" , "check" , "Hinder or delay" .)
