Fine day enveloping ladies with soft illumination (10)
I believe the answer is:
floodlight
'illumination' is the definition.
(I have seen 'Powerful illumination' mean 'floodlight' so perhaps 'illumination' could also mean 'floodlight')
'fine day enveloping ladies with soft' is the wordplay.
I cannot quite understand how this works, but
'fine' could be 'f' (abbreviation e.g. condition of old coins, books) and 'f' is found in the answer.
'day' could be 'light' (I've seen this in other clues) and 'light' is present in the answer.
'ladies' could be 'loo' (as in the ladies toilet) and 'loo' is present in the answer.
A single letter 'd' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for floodlight that I've seen before include "Means for illuminating" , "Powerful illumination" , "Sports ground illuminator" .)
