Edited merest outline giving extra time to this show? (3,2,7)
I believe the answer is:
son et lumiere
'this show?' is the definition.
(I have seen 'spectacular show' mean 'son et lumiere' so perhaps 'show' could also mean 'son et lumiere')
'edited merest outline giving extra time' is the wordplay.
I cannot quite see how this works, but
'time' could be 'one' (I've seen this before) and 'one' is found within the answer.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for son et lumiere that I've seen before include "Spectacular entertainment" , "theatrical presentation" , "Entertainment (for dark evenings)" , "Entertainment with lighting" , "spectacular show" .)
