Etymology

Origin of substantive

First recorded in 1350–1400; Middle English, from Late Latin substantīvus, equivalent to Latin substant(ia) substance + -īvus -ive

Explanation

When you talk about substantive change, you mean change that really makes a difference. After a substantive discussion, you will have an in-depth understanding of what you are talking about. When something is substantive, there is a lot of "there there," be it meaning or volume of things. The word brings a serious tone. While it is often used to talk about problems and their solutions, a big steak dinner could be called substantive, as could a very long piece of writing. In any case, you use it when there is a lot of substance involved.
