Rang the bell when urged to (7)
I believe the answer is:
pressed
'rang' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for pressed that I've seen before include "Squeezed hard" , "Forced" , "Coerced" , "Urged U crushed" , "crushed juice" .)
