Advance over in push for glory (9)
I believe the answer is:
splendour
'glory' is the definition.
(I've seen this before)
'advance over in push' is the wordplay.
I cannot really understand how this works, but
'advance' could be 'lend' (I've seen this in other clues) and 'lend' is located in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found in the answer.
'push' could be 'spur' (I've seen this in another clue) and 'spur' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for splendour that I've seen before include "Brilliant appearance" , "Magnificent appearance" , "Glory, brilliance" , "Opulence" , "show" .)
