Related Words

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.
