Cried on hearing beautiful poem? (8)
I believe the answer is:
bellowed
'cried on hearing beautiful poem?' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?
This is all the clue.
Can you help me to learn more?
(Other definitions for bellowed that I've seen before include "made loud noise" , "Roared" .)
