Recoiled from quiet boobytrap (5)
I believe the answer is:
shied
'recoiled' is the definition.
(I've seen this in another clue)
'quiet boobytrap' is the wordplay.
'quiet' becomes 'sh' (both can be said to tell someone to be quiet).
'boobytrap' becomes 'ied' (I can't justify this - if you can you should believe this answer much more).
'sh'+'ied'='SHIED'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for shied that I've seen before include "Flung, tossed" , "Jumped nervously; threw" , "started" , "Thrown" , "Cast" .)
