Advise of danger from what is pronouncedly worn (4)
I believe the answer is:
warn
'advise of danger' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for warn that I've seen before include "Sound the alarm" , "Notify of potential risk" , "Make aware of danger" , "Admonish, caution" , "Give a caution to" .)
