Did you know?

Soluble looks like a word that should be confined to chemistry labs, though it's often used by nonchemists as well to describe substances that can be dissolved in liquids. On the other hand, the sense of soluble meaning "solvable" is also quite common. In this sense, soluble, like its opposite, insoluble, is usually paired with problem. If only all life's problems were soluble by stirring them in a container filled with water.
