New union member’s restraining order for dullard (7)
I believe the answer is:
bromide
'dullard' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'new union member's restraining order' is the wordplay.
'new union member' becomes 'bride' (I've seen this before).
'restraining' means one lot of letters goes inside another.
'order' becomes 'om' (Order of Merit).
'bride' going around 'om' is 'BROMIDE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for bromide that I've seen before include "Trite fob-off" , "Platitude" , "that could send you to sleep?" , "Sedative" , "Dim bore (anag.)" .)
