Things look different after dark (6)
I believe the answer is:
nights
'things look different after dark' is the definition.
I can't judge whether this defines the answer.
'things look different' is the wordplay.
'look different' indicates anagramming the letters (I've seen 'looking different' mean this (I've seen this in other clues)).
'things' is an anagram of 'NIGHTS'.
Can you help me to learn more?
(Other definitions for nights that I've seen before include "dark times" , "Periods after sunset" , "Times of darkness" , "Periods of darkness" , "Times between days" .)
