How to say "chapter; term, semester" in Arabic

Root ف-ص-ل, 'to separate, cut off', is sometimes compared to the rare Biblical Hebrew root פ-צ-ל (Genesis 30:37, peeling strips off branches) — ص regularly answers צ. It's a thin, half-forgotten root in Hebrew but a hardworking one in Arabic: faṣl separates a school year into terms, a book into chapters, and one topic from another. The link is plausible, not proven.
