Ruined investor quit holding large position in entertainment sector (13)
I believe the answer is:
ventriloquist
'position in entertainment sector' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'ruined investor quit holding large' is the wordplay.
'ruined' is an anagram indicator.
'holding' is an insertion indicator.
'large' becomes 'L' (eg in clothes sizes).
'investor'+'quit'='investorquit'
'investorquit' anagrammed gives 'ventrioquist'.
'ventrioquist' going around 'l' is 'VENTRILOQUIST'.
Can you help me to learn more?
(Other definitions for ventriloquist that I've seen before include "Dummy operator" , "Voice-thrower" , "Performer with dummy" .)
