Token of affection almost returned, but interrupted by fish and chips? (4,5)
I believe the answer is:
side order
'token of affection almost returned but interrupted' is the definition.
I can't judge whether this defines the answer.
'by fish and chips?' is the wordplay.
'by' becomes 'side' (synonyms).
'fish and chips?' becomes 'order' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'side'+'order'='SIDE ORDER'
Can you help me to learn more?
(Another definition for side order that I've seen is " dish".)
