Etymology

Origin of substance

First recorded in 1250–1300; Middle English, from Latin substantia “substance, essence” (literally, “that which stands under, i.e., underlies”), equivalent to sub- “under, beneath” + -stant- (stem of stāns, present participle of stāre “to stand”) + -ia noun suffix; see sub-, stand, -ia; see also -ance

Explanation

Any material that possesses physical properties is called a substance. The word also refers to the gist or main idea of something. If you remember the main point of a lesson, you've got the substance. The meaning of the noun substance has evolved over time, yet it has always been related to something sound and solid — from the Latin root substare, which means "to stand firm," to the Middle English definition as an "essential nature." Nowadays, we use the word to define someone who possesses honesty and intelligence, or when we examine a message to find its essence. To be thought of as a "person of substance" is a good thing, but to be thought of as a "substance abuser" is not so good.
