Fruit container, nearly new, in boat (6)
I believe the answer is:
punnet
'fruit container' is the definition.
'punnet' can be an answer for 'container' (punnet is a kind of container). I am unsure of the 'fruit' bit.
'nearly new in boat' is the wordplay.
'nearly' means to remove the last letter.
'in' indicates putting letters inside.
'boat' becomes 'punt' (type of boat).
'new' with its last letter removed is 'ne'.
'ne' inserted into 'punt' is 'PUNNET'.
Can you help me to learn more?
(Other definitions for punnet that I've seen before include "Strawberry etc. container" , "Small light basket, for strawberries say" , "Source of fruit" , "Shallow fruit basket" , "Small basket for measuring fruit" .)
