Singular thing to eat with a cold joint (4)
I believe the answer is:
chip
'singular thing to eat' is the definition.
I can't judge whether this defines the answer.
'with a cold joint' is the wordplay.
'with' means one lot of letters go next to another.
'a cold' becomes 'c' (eg on taps).
'joint' becomes 'hip' (part of body).
'c' put next to 'hip' is 'CHIP'.
Can you help me to learn more?
(Other definitions for chip that I've seen before include "Pare" , "Small fragment (of potato?)" , "Piece of fried potato" , "Murphy sliced" , "Small piece broken off something" .)
