Food not touched when bishop leaves victorious (7)
I believe the answer is:
uneaten
'food not touched' is the definition.
I can't tell whether this defines the answer.
'bishop leaves victorious' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'leaves' suggests deleting specific letters.
'victorious' becomes 'unbeaten' (I've seen this before).
'unbeaten' with 'b' taken out is 'UNEATEN'.
'when' is the link.
Can you help me to learn more?
(Other definitions for uneaten that I've seen before include "Not consumed as food" , "Make an outline of" , "still on the table?" , "Left on the plate" , "Left after dinner" .)
