Funnel (6)
I believe the answer is:
hopper
'funnel' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hopper that I've seen before include "Insect that jumps, maybe on grass" , "Kentish farm" , "Funnel (eg, feeding grain to mill)" , "Jumper on one foot" , "skipper" .)
