Old adore ridiculously wealthy place (8)
I believe the answer is:
eldorado
'wealthy place' is the definition.
'Eldorado' can be an answer for 'place' (mythical golden city). I am not certain of the 'wealthy' bit.
'old adore ridiculously' is the wordplay.
'ridiculously' is an anagram indicator.
'old'+'adore'='oldadore'
'oldadore' anagrammed gives 'ELDORADO'.
Can you help me to learn more?
(Other definitions for eldorado that I've seen before include "city, apparently lost" , "The golden land?" , "source of wealth" , "rich land, so many thought" , "city of riches" .)
