Natural illumination in view across one French lake (8)
I believe the answer is:
sunlight
'natural illumination' is the definition.
'sunlight' can be an answer for 'illumination' (I have seen 'Solar illumination ' mean 'sunlight' so perhaps 'illumination' could also mean 'sunlight'). I'm not certain of the 'natural' bit.
'view across one french lake' is the wordplay.
'view' becomes 'sight' (synonyms).
'across' is an insertion indicator.
'one french' becomes 'un'.
'lake' becomes 'l'.
'un'+'l'='unl'
'sight' placed around 'unl' is 'SUNLIGHT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for sunlight that I've seen before include "Form of illumination" , "Solar illumination" , "What's illuminating, naturally" , "port?" , "Solar rays" .)
