Plays down article on consumer electronics trade show (6)
I believe the answer is:
dances
'consumer electronics trade show' is the definition.
I can't judge whether this defines the answer.
'plays down article on' is the wordplay.
'plays' becomes 'ces' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'down' becomes 'd'.
'article' becomes 'an' (indefinite article).
'on' is a charade indicator (letters next to each other).
'd'+'an'='dan'
'ces' after 'dan' is 'DANCES'.
Can you help me to learn more?
(Other definitions for dances that I've seen before include "Set movements to music" , "Jigs" , "Moves to music" , "Balls" , "Ascend (anag)" .)
