Ice-cream ____ (4)
I believe the answer is:
cone
'ice-cream' is the definition.
(I've seen this in other clues)
This is all the clue.
(Other definitions for cone that I've seen before include "Ice-cream cornet" , "Circular pyramid" , "99, maybe" , "Movable plastic bollard" , "Geometrical figure (used on roads!)" .)
