Resort missing out on a turn to shine (7)
I believe the answer is:
spangle
'to shine' is the definition.
(I know that spangle is a kind of gleam)
'resort missing out on a turn' is the wordplay.
'resort' becomes 'spa' (spa is a kind of resort).
'missing out on' is a deletion indicator.
'turn' becomes 'angle' (I can't justify this - if you can you should believe this answer much more).
'spa' with 'a' removed is 'sp'.
'sp'+'angle'='SPANGLE'
Can you help me to learn more?
(Other definitions for spangle that I've seen before include "Colourful spot" , "glitter" , "Sparkling" , "metal plate" , "Glittering ornament" .)
