Fruit to worry about, having to be packed into vehicle (10)
I believe the answer is:
loganberry
'fruit' is the definition.
(I know that loganberry is a type of soft fruits)
'worry about having to be packed into vehicle' is the wordplay.
I cannot really understand how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
'be' is within the answer.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for loganberry that I've seen before include "Hybrid fruit plant" , "Edible soft red fruit" .)
