When do the lights go on? It's almost time (5)
I believe the answer is:
night
'when do the lights go on?' is the definition.
I can't judge whether this definition defines the answer.
'almost time' is the wordplay.
'almost' becomes 'nigh' (nigh can mean almost or nearly).
'time' becomes 't' (abbreviation).
'nigh'+'t'='NIGHT'
'it's' is the link.
Can you help me to learn more?
(Other definitions for night that I've seen before include "The dark time" , "''Twas the ... before Christmas, when all through the house / Not a creature was stirring, not even a mouse''" , "That's when it's darkest" , "late" , "Time between days" .)
