Our chap in Panama is evidently backward (3)
I believe the answer is:
man
'our chap' is the definition.
I can't judge whether this defines the answer.
'in panama is evidently backward' is the wordplay.
'in' indicates a hidden word.
'backward' says the letters should be written backwards.
'nam' is hidden in the letters of 'panama evidently'.
'nam' written backwards gives 'MAN'.
Can you help me to learn more?
(Other definitions for man that I've seen before include "just one" , "knight, perhaps?" , "Isle of -; chess piece" , "Provide with crew" , "The most destructive and polluting animal" .)
