Papal publication — something to beware of? (4)
I believe the answer is:
bull
'papal publication' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bull that I've seen before include "Male whale" , "Male elephant, say" , "Slangy lies from an ox?" , "Dartboard's centre" , "Male charging" .)
