With end of snout, collar the French delicacy (7)
I believe the answer is:
truffle
'delicacy' is the definition.
(truffle is a kind of delicacy)
'with end of snout collar the french' is the wordplay.
'with end of snout' becomes 't' (I can't explain this - if you can you should believe this answer much more).
'collar' becomes 'ruff' (ruff is a kind of collar).
'the french' becomes 'le'.
't'+'ruff'+'le'='TRUFFLE'
Can you help me to learn more?
(Other definitions for truffle that I've seen before include "Chocolaty sweet" , "Fungoid delicacy" , "Edible fungus -- chocolate sweet" , "Soft chocolate; fungus" , "Witty remark" .)
