Verb

  1. to divide society or a group into distinct classes or levels

  2. to form, separate, or arrange into distinct layers or strata

  3. to divide a sample, population, or patients into subgroups before analysis or treatment

Beyond the definition

Imagine a beautiful layered cake - that gives you the basic idea. To stratify means to arrange or separate things into clear layers, levels, or groups, often based on shared features. Geologists talk about rock layers being stratified over millions of years, and sociologists discuss how society can be stratified by wealth or social class. It is not only about physical layers, though; you can also stratify information by putting it into groups so it is easier to understand. Think of sorting emails into folders - that is a simple example.
