matter

v. be important, be significant

n. physical material (as opposed to spiritual); substance of a particular composition and consistency; issue, affair; excreted material; typed or written material; something that has mass and takes up space

In chemistry and physics, matter is commonly defined as the substance of which physical objects are composed, not counting the contribution of various energy or force-fields, which are not usually considered to be matter per se (though they may contribute to the mass of objects). Matter constitutes much of the observable universe, although again, light is not ordinarily considered matter. Unfortunately, for scientific purposes, "matter" is somewhat loosely defined.
