Prepare for action (e.g., some mousetraps) (3)
I believe the answer is:
set
'prepare' is the definition.
(I know that prepare can be written as set)
'action e g some mousetraps' is the wordplay.
'SET' is hidden in amongst the letters.
However, I am unsure how this is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for set that I've seen before include "Ready" , "Put, coagulate" , "Class" , "Arrange; a party" , "Major division of tennis match" .)
