Connoisseur round home is money expert (9)
I believe the answer is:
financier
'money expert' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'connoisseur round home' is the wordplay.
'connoisseur' becomes 'fancier' (I've seen this in another clue).
'round' is an insertion indicator.
'home' becomes 'in' ('he's home' can mean 'he's in').
'fancier' placed around 'in' is 'FINANCIER'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for financier that I've seen before include "One dealing in big money" , "Businessman" , "moneyman" , "Investor" , "Money manager" .)
