Stick one's nose in, hearing gong, perhaps (6)
I believe the answer is:
meddle
'stick one's nose in' is the definition.
(both can mean to interfere with something)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for meddle that I've seen before include "Interfere in the affairs of others" , "Interfere unnecessarily" , "Pink Floyd album" , "Interfere in people's affairs" , "Intrude in other people's affairs" .)
