Crimson water? (4)
I believe the answer is:
lake
This clue could be a double definition.
'crimson' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'water?' is the second definition.
(I know that water can be written as lake)
Can you help me to learn more?
(Other definitions for lake that I've seen before include "holiday up north" , "Large pond; pigment" , "Pool" , "Inland body of water" , "Erie, perhaps" .)
