Provided fine canned food for one? (6)
I believe the answer is:
tiffin
'food for one?' is the definition.
I know that 'food' relates to this answer.
'provided fine canned' is the wordplay.
I cannot really understand how this works, but
'provided' could be 'if' (eg 'provided it's sunny' means 'if it's sunny') and 'if' is found within the answer.
'fine' could be 'f' (abbreviation) and 'f' is found within the answer.
The remaining letters 'tin' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tiffin that I've seen before include "(Anglo Indian) lunch" , "Anglo-Indian lunch" , "Light Indian repast" , "Snack, light meal (dated)" , "Indian midday meal" .)
