Fuss after the Spanish note gold here? (8)
I believe the answer is:
eldorado
'here?' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'fuss after the spanish note gold' is the wordplay.
'fuss' becomes 'ado' ('ado' can be a synonym of 'fuss'**).
'after' means one lot of letters go next to another.
'the spanish' becomes 'el'.
'note' becomes 'd' (musical note).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'el'+'d'+'or'='eldor'
'ado' put after 'eldor' is 'ELDORADO'.
(Other definitions for eldorado that I've seen before include "city, apparently lost" , "rich land, so many thought" , "The golden land?" , "source of wealth" , "city of riches" .)
