Earlier I replied and showed a snapshot of the history. Contemporary: https://www.freebsd.org/cgi/man.cgi All Sections https://man.openbsd.org All Sections A random Oracle man page for SunOS: man pages section 2: System Calls https://developer.apple.com/documentation/os/reading_unix_manual_pages "Section 1 of the man pages covers command-line tools, section 2 covers system calls, section 3 covers user-space libraries, and so on." Etc. It may be true that there was historical use of "chapter", but all common places today have "section". Andries
