Water, in France (3)
I believe the answer is:
eau
'water in france' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eau that I've seen before include "French water - de Cologne?" , "French water, may be Cologne" , "Popular toilet water - . . . de Cologne" , "Perrier water" , "Quick to notice things" .)
