English cavalryman's eating -- say grace (8)
I believe the answer is:
elegance
'grace' is the definition.
(I've seen this in another clue)
'english cavalryman's eating say' is the wordplay.
'english cavalryman' becomes 'elance' (I can't justify this - if you can you should believe this answer much more).
'eating' indicates putting letters inside.
'say' becomes 'eg' (both can mean 'for example').
'elance' going around 'eg' is 'ELEGANCE'.
Can you help me to learn more?
(Other definitions for elegance that I've seen before include "Sophistication" , "Gracefulness" , "Graceful style" , "Showing good taste in dress or style" , "Refinement in taste and dress" .)
