To demarcate is to decide or mark the limits of something — a piece of land, a country line, a system, a job, a topic. You can demarcate with a fence or a river, and you can also demarcate in talk: “Let's demarcate what this team does and what that team does.” It is a formal verb; in daily speech people often say mark off, set the limits, or draw the line. The noun you will meet beside it is demarcation (a demarcation line). It is about where one thing stops and another starts, not about making something look pretty.
