Senate group renowned for giving a hoot (10)
I believe the answer is:
parliament
'senate' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for parliament that I've seen before include "UK legislature" , "The law is laid down here" , "Diet" , "Houses" , "Legislative body" .)
