matter

Matter is everywhere: anything that has mass and takes up space is matter. Air? Donuts? People? Buildings? Melted butter? All of these, and much, much more, are matter.

Other kinds of matter don't have a physical form, like a concern, problem, or even something that people think about, like a worrisome money matter, a personal matter, or a movie with a particular subject matter. Matter can also be a verb, meaning "to be important," as in: "Good health matters to me."
