A catchword is a word or brief phrase inscribed at the base of a page in a handwritten or printed codex, placed there by the scribe or printer to ensure correct folio ordering during gathering and collation. Parameters: (1) a lexical token matching the opening word of the succeeding page, (2) positioned at the bottom margin of the verso or recto, (3) produced as part of the bookmaking workflow. Persistence mechanism: established through scribal convention, codified in printing house practices, and maintained by bookbinders and librarians who verify page order by reading catchwords during binding.

Definition
Why it is in scope

Built to persist through scribal practice, printing conventions, and library cataloging systems.

A catchword is a typographic convention where a word appears at page breaks for navigation; it needs language to function — without language the practice collapses.

Remove books from the world right now and catchwords — words placed at the bottom of pages for pagination verification — lose all function. The removal test passes: catchwords operate only within the practice of book production. Catchword (epoch 0.15) predates book (0.73), but present-day dependency doesn't require which-came-first.

A catchword is a specific kind of word — one chosen for its ability to summarize a topic, attract attention, or serve as a mnemonic. A competent speaker would call it 'a type of word' (specifically, a word used in a particular way). This files against the nearest existing kind.
