Rubbish can be left in large receptacle at the end (5)
I believe the answer is:
bilge
'rubbish' is the definition.
(I've seen this before)
'can be left in large receptacle at the end' is the wordplay.
'can be left' becomes 'l' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'large' becomes 'big' ('big' can be a synonym of 'large').
'at the end' suggests the final letters.
The final letter of 'receptacle' is 'e'.
'l' going within 'big' is 'bilg'.
'bilg'+'e'='BILGE'
Can you help me to learn more?
(Other definitions for bilge that I've seen before include "Filthy water that collects in the bottom of a boat" , "Lowest internal portion of a ship's hull" , "Very long film, book etc" , "Dirty water collecting on a vessel" , "Rubbish - water in boat" .)
