Present-day conclusion? (7)
I believe the answer is:
tonight
'present' is the definition.
(I know that tonight is a type of present)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for tonight that I've seen before include "Late today" , "What follows today" , "Got thin (anag)" , "Later this evening" , "Hotting up for after sundown" .)
