What is the meaning of the word circumscribe?

The term "circumscribe" refers to the act of enclosing something within certain boundaries or limits. This can involve drawing a line around an object or defining a space. In mathematical contexts, for example, a circle can circumscribe a polygon if it touches all the vertices of the polygon without breaking that boundary. This concept of restricting or confining something is encapsulated in the choice of "enclose," which accurately conveys the essence of what it means to circumscribe.
