A resounding decoration? (4)
I believe the answer is:
gong
'decoration?' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for gong that I've seen before include "Kind of bell sounded for dinner" , "Wordsworth's Boy; Dostoevsky's hero" , "Sound announcing meal" , "Decoration" , "Source of summons" .)
