Vessel for small fruit (4)
I believe the answer is:
ship
'vessel' is the definition.
(I know that ship is a type of vessel)
'small fruit' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'fruit' becomes 'hip' (the fruit of a rose).
's'+'hip'='SHIP'
'for' is the link.
(Other definitions for ship that I've seen before include "Vessel that carries passengers or freight" , "Large sailing vessel" , "Sea-going craft" , "Take on" , "Ocean vessel" .)
