Introduction to Lily Savage overwhelms celebrity (5)
I believe the answer is:
glory
'celebrity' is the definition.
(I've seen this in another clue)
'introduction to lily savage overwhelms' is the wordplay.
'introduction to' indicates taking the first letters.
'savage' becomes 'gory' (I can't explain this - if you can you should give a lot more credence to this answer).
'overwhelms' is an insertion indicator.
The first letter of 'lily' is 'l'.
'l' placed inside 'gory' is 'GLORY'.
Can you help me to learn more?
(Other definitions for glory that I've seen before include "Resplendent brightness" , "Magnificence" , "widespread praise" , "See 8" , "The Power and the . . . . . (Graham Greene)" .)
