Utter a sad broadcast, soaking (9)
I believe the answer is:
saturated
'soaking' is the definition.
(synonyms)
'utter a sad broadcast' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'utter'+'a'+'sad'='utterasad'
'utterasad' with letters rearranged gives 'SATURATED'.
(Other definitions for saturated that I've seen before include "dripping" , "Drenched" , "Imbued" , "Sodden" , "Thoroughly soaked" .)
