Noise from family group beginning to grate (5)
I believe the answer is:
clang
'noise' is the definition.
(clang is a kind of noise)
'family group beginning to grate' is the wordplay.
'family group' becomes 'clan' (I've seen this before).
'beginning to' says to take the initial letters.
The first letter of 'grate' is 'g'.
'clan'+'g'='CLANG'
'from' is the link.
(Other definitions for clang that I've seen before include "Loud resonant metallic sound" , "Noise as of cymbals" , "Jangle" , "A loud ringing sound" , "Dull sound of a bell" .)
