Richness of incentive securing advance orders to begin with (9)
I believe the answer is:
splendour
'richness' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'incentive securing advance orders to begin with' is the wordplay.
'incentive' becomes 'spur' (spur can mean an incentive or stimulus).
'securing' means one lot of letters goes inside another.
'advance' becomes 'lend' (I've seen this in another clue).
'to begin with' indicates taking the first letters.
The first letter of 'orders' is 'o'.
'lend'+'o'='lendo'
'spur' placed around 'lendo' is 'SPLENDOUR'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for splendour that I've seen before include "Spectacle" , "Opulence" , "Brilliance or pomp" , "Glory, brilliance" , "Magnificent appearance" .)
