Still water? (7)
I believe the answer is:
pacific
I believe this clue is a double definition.
'still' is the first definition.
(thesaurus)
'water?' is the second definition.
(Pacific is an example)
(Other definitions for pacific that I've seen before include "Avoiding conflict" , "Calm - ocean" , "A great ocean" , "Non-combative" , "Ecuador's ocean" .)
