“Listen to Ria”— News shows booming (10)
I believe the answer is:
stentorian
'booming' is the definition.
(synonyms)
'listen to ria-news shows' is the wordplay.
'shows' indicates a hidden word.
'STENTORIAN' is hidden in the letters of 'listen to ria news'.
(Other definitions for stentorian that I've seen before include "booming" , "Strident" , "(Of a person's voice) loud and powerful" .)
