Encourages about bomb containers (9)
I believe the answer is:
eggshells
'containers' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how one could define the other.
'encourages about bomb' is the wordplay.
'encourages' becomes 'eggs'.
'about' indicates putting letters inside.
'bomb' becomes 'shell' (shelling is a kind of bombing).
'eggs' placed around 'shell' is 'EGGSHELLS'.
Can you help me to learn more?
(Other definitions for eggshells that I've seen before include "Tip-toe gently like walking on ........." , "They're hard to hold yolks" , "Walk delicately as if on these" , "See 1" .)
