Rubbish outing closer to night-time (5)
I believe the answer is:
tripe
'rubbish outing' is the definition.
'tripe' can be an answer for 'rubbish' (both can mean nonsense). I am unsure of the 'outing' bit.
'closer to night-time' is the wordplay.
'closer to' suggests the final letters (the letter which ends or closes the word).
'time' becomes 'ripe' (I am not sure about this - if you are sure you should believe this answer much more).
The last letter of 'night' is 't'.
't'+'ripe'='TRIPE'
Can you help me to learn more?
(Other definitions for tripe that I've seen before include "What some northerners eat" , "Edible lining of cow's stomach - rubbish" , "Ruminant's stomach lining" , "Rhubarb" , "Pants" .)
