Ringing about issue with social worker (8)
I believe the answer is:
resonant
'ringing' is the definition.
(thesaurus)
'about issue with social worker' is the wordplay.
'about' becomes 're' (regarding**).
'issue' becomes 'son' (issue can mean someone's offspring).
'with' is a charade indicator (letters next to each other).
'social worker' becomes 'ant' (I've seen this before).
're'+'son'+'ant'='RESONANT'
(Other definitions for resonant that I've seen before include "producing vibrant sound" , "Re-echoing" , "(Of sound) deep and ringing" , "Tending to reinforce sounds" , "Booming" .)
