Receptacle in circle that is black at home (7,3)
I believe the answer is:
wheelie bin
'receptacle' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'circle that is black at home' is the wordplay.
'circle' becomes 'wheel' (wheel can mean to circle or turn).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'black' becomes 'b' (as in pencil classifications).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'wheel'+'ie'+'b'+'in'='WHEELIE BIN'
'in' is the link.
Can you help me to learn more?
(Other definitions for wheelie bin that I've seen before include "dirty vessel" , "Moveable garbage container" , "Portable refuse collector" .)
