Former TV channel brought in broadcast of Caruso looking gaunt (10)
I believe the answer is:
cadaverous
'gaunt' is the definition.
(synonyms)
'former tv channel brought in broadcast of caruso' is the wordplay.
'former tv channel' becomes 'dave' (I am not sure about this - if you are sure you should believe this answer much more).
'brought in' indicates putting letters inside.
'broadcast of' indicates anagramming the letters (I've seen 'broadcast' mean this (letters scattered or cast around)).
'caruso' is an anagram of 'carous'.
'dave' going into 'carous' is 'CADAVEROUS'.
'looking' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for cadaverous that I've seen before include "Unhealthy-looking" , "not looking healthy" , "Skeletal" , "Resembling a corpse" , "Ghastly" .)
