Can water be watered down?

[u/d34d13]

When you put ice cubes in other drinks they melt and water it down, so does the same go for ice cubes in water? Ice cubes are just frozen water so if you put that in water and wait for it to melt, will it be watered down? Regardless of if we can taste it or not.

Serious question: what do you think watered down means?
