substance
word
Definition
A substance is a particular kind of material or matter, such as a liquid, powder, or chemical. It can also mean the real meaning, value, or importance of something, not just its appearance.
Usage & Nuances
Common in science and formal writing for physical materials: 'a dangerous substance', 'chemical substance'. In more abstract use, 'with substance' means meaningful or serious, while 'lack substance' means shallow or unsupported. Don't confuse it with 'material': 'substance' often sounds more technical or abstract.
