Going in punt, ask for picnic hamper (6)
I believe the answer is:
basket
'picnic hamper' is the definition.
'basket' can be an answer for 'hamper' (I've seen this before). I am not sure about the 'picnic' bit.
'going in punt ask' is the wordplay.
'going in' is an insertion indicator.
'punt' becomes 'bet' (I've seen this in other clues).
'bet' placed around 'ask' is 'BASKET'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for basket that I've seen before include "Woven container for carrying food etc" , "Container of woven twigs etc" , "See 10" , "''Don't put all your eggs in one . . . . . .''" , "case" .)
