Shouted, bellowed (6)
I believe the answer is:
yelled
I believe this is a double definition.
'shouted' is the first definition.
(yelling is a kind of shouting)
'bellowed' is the second definition.
(I've seen this in another clue)
(Other definitions for yelled that I've seen before include "Cried out, hollered" , "Shouted loudly as if to be heard" , "Screamed" , "Uttered a sudden loud cry" , "Uttered a sharp loud cry" .)
