Lightweight packaging for swift delivery? (8)
I believe the answer is:
eggshell
This clue might be a double definition.
'lightweight packaging' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'swift delivery?' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for eggshell that I've seen before include "(Of paint) having a very slight sheen" , "destined to be cracked?" , "Thin and delicate" , "made in Dorking?" , "Fine finish" .)
