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 a hidden word.
'IMPEDE' can be found hidden inside '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" .)
