To make something dense or denser; to compress or thicken something.
From Latin densus (thick, close) + -ate (suffix forming verbs). Densate is a technical or rare verb used especially in scientific contexts to describe the process of increasing density.
You won't hear 'densate' in everyday speech, but physicists and engineers use it precisely—when you compress a gas into a liquid, you're densating it, and in chemistry the process of densation changes everything about how molecules interact.
