She will prepare the peas (5)
I believe the answer is:
shell
'prepare the peas' is the definition.
I can't tell whether this defines the answer.
'she will' is the wordplay.
'will' becomes 'll'.
'she'+'ll'='SHELL'
Can you help me to learn more?
(Other definitions for shell that I've seen before include "Hard protective case" , "Explosive projectile" , "cover" , "Conch, perhaps" , "ammunition" .)
