What Does ‘what is the substance’ Mean?
At its core, the question what is the substance asks: what is the essential stuff here, literally or figuratively. In everyday speech it often asks for the main point. In science it asks for composition. In law it asks for the material facts or the crucial element of an offense.
So the meaning changes with context, but the thread is the same: the asker wants to separate surface detail from what truly matters. Answerers who recognize that get to the heart of the matter faster.
Etymology and Origin of the Question
The word substance comes from Latin substantia, meaning ‘that which stands under’, formed from sub meaning ‘under’ and stans meaning ‘standing’. Philosophers in the Middle Ages used substance to mean the underlying reality that supports properties.
As a question, what is the substance has older cousins in philosophical Latin and Greek, but its everyday use—asking for composition or core meaning—became common as scientific classification and legal reasoning developed in the 17th and 18th centuries. You can track the dictionary definition of substance at Merriam-Webster and see the philosophical entry at Wikipedia.

‘what is the substance’ in Different Contexts
Science: Chemists answer the question by naming elements and compounds, percentages, and molecular structure. If someone asks what is the substance spilled on the lab bench, identification might involve spectroscopy or a simple pH test.
Law: Lawyers use the phrase to demand the material facts. Judges care about the substance of a claim more than rhetorical flourishes. For basic legal definitions, see Britannica or a law text.
Philosophy: Here substance is an ontological term meaning what underpins properties. Metaphysicians debate whether substances are necessary to explain change and identity over time.

Common Misconceptions About the Question
One misconception is that asking what is the substance is always about physical matter. Not so. Often it is shorthand for ‘what is the main point’. Context is the signpost. Misread the context and you answer the wrong question.
Another mistake is assuming substance equals value. Something can be substantial without being valuable, and vice versa. A three-page legal brief might contain important substance even if it is poorly written.
