Splendour of industrial plant about to be demolished (6)
I believe the answer is:
finery
'splendour of industrial plant' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for finery that I've seen before include "Elaborate clothing, jewellery etc" , "Fancy clothes or trappings" , "Ostentatious decoration" , "Showy clothing" , "Ostentatious clothing" .)
