Stick one’s nose in, hearing gong (6)
I believe the answer is:
'nose in hearing gong' is the definition.
'meddle' can be an answer for 'nose' (thesaurus). I am not sure about the 'in hearing gong' bit.
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 "Intrude, interfere" , "Stick one's oar in" , "Interfere in other people's business" , "Interfere unnecessarily" , "Intervene" .)
