Etymology

Origin of chapter

1175–1225; Middle English chapiter, variant of chapitre < Old French < Latin capitulum little head ( capit-, stem of caput head + -ulum -ule ); in Late Latin: section of a book; in Medieval Latin: section read at a meeting, hence, the meeting, especially one of canons, hence, a body of canons

Explanation

A chapter is a section of a book. Some long novels might be divided into twenty or thirty chapters. The noun chapter is good for talking about a subset or small section of some larger thing. Book chapters are one example, and so is a chapter in a person's life or a chapter of an organization or club. When you mention the "mopey teenage chapter" of your life, you mean one small portion of the years you've lived. And the Montana chapter of a national fan club is made up of only members who live in one state.
