Inscrutable European Community should welcome reformed Tories (8)
I believe the answer is:
esoteric
'inscrutable' is the definition.
(I've seen this in another clue)
'should welcome reformed tories' is the wordplay.
'should' becomes 'ec' (I am not sure about this - if you are sure you should believe this answer much more).
'welcome' indicates putting letters inside (in sense of 'inviting in').
'reformed' indicates anagramming the letters.
'tories' anagrammed gives 'soteri'.
'ec' placed around 'soteri' is 'ESOTERIC'.
'european community' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for esoteric that I've seen before include "Taught to a select few" , "I set core up to be mysterious" , "not generally understood" , "Intelligible only with special knowledge" , "hidden" .)
