Held to rhyme with 'howled' (6)
I believe the answer is:
yelled
'howled' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for yelled that I've seen before include "made a lot of noise" , "Uttered a sudden loud cry" , "Cried out, hollered" , "Called" , "Screamed" .)
