Scottish group good for ringing sound (5)
I believe the answer is:
clang
'ringing sound' is the definition.
(I've seen this before)
'scottish group good' is the wordplay.
'scottish group' becomes 'clan' (family or group of families in Scotland).
'good' becomes 'g' (abbreviation).
'clan'+'g'='CLANG'
'for' is the link.
(Other definitions for clang that I've seen before include "Resounding effect" , "heavy metal sound" , "Make a loud metallic noise" , "Ring of metal" , "Ring loud and deep" .)
