Devised scare and obtained a delicacy (8)
I believe the answer is:
'a delicacy' is the definition.
(I have seen 'French delicacy' mean 'escargot' so perhaps 'delicacy' could also mean 'escargot')
'devised scare and obtained' is the wordplay.
'devised' indicates an anagram.
'and' is a charade indicator (letters next to each other).
'obtained' becomes 'got' ('get' can be a synonym of 'obtain').
'scare' anagrammed gives 'escar'.
(Other definitions for escargot that I've seen before include "One continually moving house" , "French delicacy" , "French food" , "Cart goes carrying edible French snail" , "An edible snail from France" .)
