Case of luxurious rings made of gold for distinguished people (9)
I believe the answer is:
laureates
'distinguished people' is the definition.
'laureates' can be an answer for 'people' (laureate is a kind of person). I'm not certain of the 'distinguished' bit.
'case of luxurious rings made of gold' is the wordplay.
'case of' means to remove the middle letters (outsides of).
'rings' is an insertion indicator (some letters are ringed or contained by others).
'made of gold' becomes 'aureate' (I am not sure about this - if you are sure you should believe this answer much more).
'luxurious' with its middle removed is 'ls'.
'ls' enclosing 'aureate' is 'LAUREATES'.
'for' is the link.
Can you help me to learn more?
(Other definitions for laureates that I've seen before include "Special poets are honoured people" , "eminent poets" .)
