Concerning a woman and possibly Christopher (5)
I believe the answer is:
reeve
'possibly christopher' is the definition.
I can't judge whether this defines the answer.
'concerning a woman' is the wordplay.
'concerning' becomes 're'.
'a woman' becomes 'eve' (Eve is an example).
're'+'eve'='REEVE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for reeve that I've seen before include "Bird - female of the ruff" , "Old-style magistrate" , "Pass cable through narrow opening" , "magistrate of long ago" , "Old magistrate or official" .)
