Explosive kick can set up breaks (6)
I believe the answer is:
tonite
'explosive' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'kick can set up breaks' is the wordplay.
'kick' becomes 'toe' (I've seen this before).
'can' becomes 'tin' (synonyms).
'set up' shows that the letters should be reversed in order.
'breaks' indicates putting letters inside.
'tin' reversed gives 'nit'.
'toe' enclosing 'nit' is 'TONITE'.
Can you help me to learn more?
(Other definitions for tonite that I've seen before include "Blasting explosive" , "This causes blasts" .)
