This French lake has a man's name (5)
I believe the answer is:
cecil
This might be a double definition.
'this french lake' is the first definition.
The definition suggests a singular noun which matches the answer.
'a man's name' is the second definition.
(I've seen this before)
'has' is the link.
Can you help me to learn more?
(Other definitions for cecil that I've seen before include "Man" , "Marquis of Salisbury family name" , "& 24 Across Colonialist in South Africa" , "Boy's name" , "Nobleman" .)
