substance
/ΛsΚbstΙns/
The word revolves around the concept of 'weight'βwhether that weight is physical, intellectual, or financial. It describes something that is not hollow, fleeting, or superficial. In a scientific context, it refers to the tangible makeup of matter. Unlike "material," which often implies what something is made of for a purpose, "substance" focuses on the chemical or physical identity of the matter itself. When applied to ideas or arguments, it contrasts sharply with "style" or "fluff." A person's argument has substance if it is backed by evidence and logic rather than just rhetoric. It conveys a sense of durability and depth. In social contexts, referring to someone as a "person of substance" evokes an old-fashioned sense of stability and prestige, implying they possess the financial means to influence their environment.
Countable when referring to a specific chemical or material ('a toxic substance'). Uncountable when referring to the quality of being solid, the core meaning of an argument, or general wealth ('a man of substance').
