Stentorian (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
loud
'stentorian' is the definition.
(similar in meaning)
This is all the clue.
(Other definitions for loud that I've seen before include "This speaker is" , "At high volume" , "Noisy or garish" , "Brash" , "like the bees in Yeats's glade?" .)
