They go round doing the decorating for certain members (7)
I believe the answer is:
bangles
'certain members' is the definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.
'they go round doing the decorating' is the wordplay.
I cannot quite understand how this works, but
'go' could be 'angle' (angling is a kind of going) and 'angle' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for bangles that I've seen before include "Ornaments" , "Baubles, - - , and beads" .)
