Rings about child at rest centre (9)
I believe the answer is:
resonates
'rings' is the definition.
(I've seen this before)
'about child at rest centre' is the wordplay.
'about' indicates putting letters inside.
'child' becomes 'son' (male child).
'rest centre' becomes 'rees' (I can't explain this - if you can you should believe this answer much more).
'son'+'at'='sonat'
'sonat' placed into 'rees' is 'RESONATES'.
Can you help me to learn more?
(Other definitions for resonates that I've seen before include "reverberates" , "Rings" , "Resounds" .)
