Nisaba · the lexicon

Purpose#

Word study for one headword (fixture: ἡγεμονικόν). Surfaces morphology (declension), etymology, glosses across the corpus, attestations, and semantic field.

Entry points#

• Nisaba sub-nav — LSubNav entry "Lexicon" on nisaba.md
• Daily passage — "↗ lexicon" affordance on nisaba-daily.md
• Concept graph node — nisaba-graph.md concept nodes open lexicon entries (verify exact wiring)
• Direct URL / bookmark — yes

Layout regions#

page.tsx is a thin server component: await getNisabaLexicon() → <NisabaLexicon data={data} />.

Inside NisabaLexicon (nisaba.tsx, line 1080):

• Web shell top — LCustomerNav active="library"
• Header strip — eyebrow row "Nisaba · the lexicon" / "Word study · Greek · headword" / "← σχολή · ἡγεμονικόν · θεωρία →"
• Hero word block — large serif headword (size 84), transliteration ("hēgemonikón"), italic gloss ("n. · the ruling part, the governing faculty")
• Three-column body (repeat(3, 1fr)):
  • I · Morphology — the word, declined. — case / singular / plural table driven by data.declension
  • II · … — etymology / glosses across the corpus (verify in source)
  • III · … — attestations, semantic field (verify in source)
• Footer / cross-references — verify in source

States#

• Loaded — getNisabaLexicon() resolves before render
• Headword switching — eyebrow row hints at prev/next: "← σχολή · ἡγεμονικόν · θεωρία →"; verify whether arrows are interactive
• Declension table populated — data.declension.map(row => Fragment(row[0])) renders one row per case
• Empty column — verify behavior when a section (etymology / glosses / attestations) is empty in the data
• Reduced motion — composes static Lilith primitives

Interactions#

Header strip#

• ← σχολή (previous headword) — verify whether interactive in V1
• θεωρία → (next headword) — verify

Hero word block#

• Headword glyph — non-interactive serif display
• Transliteration — non-interactive accent italic

Morphology table#

• Case label (case) — non-interactive
• Singular / plural form — verify whether each form is clickable to see attestations
• Row hover / focus — verify any hover highlighting

Other sections#

• Gloss row — verify whether glosses link to passages
• Attestation row — verify whether each attestation opens its passage in the reading desk
• Semantic-field card — verify whether related words open their own lexicon entries

Data & contracts#

• Reads: getNisabaLexicon() from @/lib/lilith-data/nisaba-depth — returns NisabaLexiconData (verify shape: declension rows, etymology, glosses, attestations, semantic-field)
• Writes: None.
• Realtime: None.
• Caching: server fetch
• Auth/role check: shell middleware

Cross-references#

• Sibling Nisaba routes:
  • nisaba.md, nisaba-compare.md, nisaba-daily.md, nisaba-graph.md, nisaba-manuscript.md, nisaba-notebook.md, nisaba-plan.md, nisaba-scholar.md
• Component sources:
  • apps/oshun/web/src/components/lilith/nisaba.tsx (NisabaLexicon line 1080)
• Feature spec: V1/features.md#nisaba

Open questions / known gaps#

• Confirm whether prev/next headword arrows in the eyebrow row are interactive in V1
• Document the cross-link contract — glosses, attestations, and semantic field destinations
• Verify reduced-motion handling for any hero animations
• Document the BFF endpoint that hydrates NisabaLexiconData once it replaces the local fixture
