Synonym Usage
Matter, material, stuff, substance refer to that of which physical objects are composed (though all these terms are also used abstractly). Matter, as distinct from mind and spirit, is a broad word that applies to anything perceived, or known to be occupying space: solid matter; gaseous matter. Material usually means some definite kind, quality, or quantity of matter, especially as intended for use: woolen material; a house built of good materials. Stuff, a less technical word, with approximately the same meanings as material, is characterized by being on an informal level when it refers to physical objects ( Dynamite is queer stuff ), and on a literary or poetic one when it is used abstractly ( the stuff that dreams are made on ). Substance is the matter that composes a thing, thought of in relation to its essential properties: a sticky substance.

Etymology
Origin of matter
First recorded in 1175–1225; Middle English mater(e), materie, from Anglo-French, Old French mat(i)ere, materie, from Latin māteria “woody part of a tree, material, substance,” derivative of māter “mother”; see also mother 1
Explanation
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."
