Caught unfortunately hugging large soprano (6)
I believe the answer is:
callas
'soprano' is the definition.
(Maria Callas)
'caught unfortunately hugging large' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'unfortunately' becomes 'alas' (I've seen this before).
'hugging' indicates putting letters inside.
'large' becomes 'l'.
'alas' enclosing 'l' is 'allas'.
'c'+'allas'='CALLAS'
(Other definitions for callas that I've seen before include "Maria - - , opera singer" , "Great Greek American soprano" , "Greek diva" , "Arguably, the greatest diva of them all" , "Maria ..., great diva of Greece" .)
