Man didn't quite swallow one piece of bread (7)
I believe the answer is:
chapati
'piece of bread' is the definition.
(chapati is a type of bread)
'man didn't quite swallow one' is the wordplay.
I cannot quite see how this works, but
'man' could be 'pat' and 'pat' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
The remaining letters 'cha' 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 chapati that I've seen before include "Sort of bread" , "What Indian waiter might bring" , "Piece of bread (Indian)" , "Indian pancake" , "I may be taken in with Indian" .)
