Abjad Graphemic Module (AGM v1.0)

---

(aka: Literal–Graphemic Module — Abjad Framework)

0) Orientation

• Script type: Abjad (consonant-first writing system; vowels absent or secondary)
• Direction: Typically right-to-left (RTL), but framework allows LTR variants in historical cases (e.g., early Phoenician inscriptions).
• Core principle: Graphemes represent consonants; vowels indicated optionally with diacritics, matres lectionis, or not at all.
• Coverage: Framework supports all known abjad families:
  • Northwest Semitic: Phoenician → Aramaic → Hebrew
  • South Semitic: Ancient South Arabian, Geʽez
  • Arabic family: Arabic → Persian, Urdu, Kurdish Sorani
  • Syriac family: Estrangela, Serto, Madnhaya
  • Maghrebi & Mashreqi variants

1) Base Consonant Layer

Abjad Core Set — abstract model of 22 consonants (Phoenician–Hebrew mapping order), adaptable to language-specific inventories:

ID	Proto Name	Base Latin Chain	Abstract Phoneme Class
1	ʾAleph	ʾ	glottal stop or mater a/e
2	Beth	b	voiced bilabial stop
3	Gimel	g	voiced velar stop/fricative
4	Daleth	d	voiced alveolar stop/fricative
5	He	h	voiceless glottal fricative / mater a
6	Waw	w	approximant / mater u/o
7	Zayin	z	alveolar fricative
8	Ḥeth	ḥ	voiceless pharyngeal fricative
9	Ṭeth	ṭ	emphatic alveolar stop
10	Yod	y	palatal approximant / mater i/e
11	Kaph	k	voiceless velar stop/fricative
12	Lamed	l	alveolar lateral
13	Mem	m	bilabial nasal
14	Nun	n	alveolar nasal
15	Samekh	s	alveolar fricative
16	ʿAyin	ʿ	voiced pharyngeal/epiglottal
17	Pe	p	voiceless bilabial stop/fricative
18	Ṣade	ṣ	emphatic alveolar fricative/affricate
19	Qoph	q	uvular stop
20	Resh	r	alveolar trill/tap
21	Shin	š	postalveolar fricative
22	Taw	t	voiceless alveolar stop/fricative

Lattice flag: {language_map: {...}} defines exact grapheme shape + phoneme realization per script/language.

2) Vowel Layer (Optional)

• Diacritic system (e.g., Arabic ḥarakāt, Hebrew niqqud, Syriac vowel points) stored as {vowel_mark: [glyph, IPA]}.
• Matres lectionis: consonant letters functioning as vowel markers:
  • Aleph → a/e
  • Waw → u/o
  • Yod → i/e
  • He (final) → a

3) Connection & Shaping Features

• {direction: RTL} (default, can set LTR for archaic inscriptions)
• {join_type: none|right|dual} for cursive scripts (Arabic-family join logic)
• {final_form: true|false} for scripts with positional variants (Hebrew finals, Arabic contextual forms)
• {style: formal|cursive|calligraphic} for shaping rules (e.g., Naskh, Nastaʿlīq, Estrangela, Maghrebi)

4) Latin-chain Mapping (Abstract Level)

glyph_id: "pe"
proto_name: "Pe"
latin_chain: ["p"]
phoneme_class: "voiceless_bilabial_stop"
features: {mater_lectionis: false}

glyph_id: "yod"
proto_name: "Yod"
latin_chain: ["y"]
phoneme_class: "palatal_approximant"
features: {mater_lectionis: true, vowels: ["i","e"]}

5) Sample Implementation in Child Scripts

Arabic: Pe absent natively; Persian/Urdu add پ to map /p/ into slot 17.
Hebrew: Kaph has dagesh toggle /kχ/.
Syriac: Beth has quššāyā vs rukkākhā toggle /bv/.

---

6) Example Word Decomposition (Abstract)

• Root K–T–B (“to write”):
  • Hebrew: כתב → kaf (k) + tav (t) + bet (b)
  • Arabic: كتب → kāf (k) + tāʾ (t) + bāʾ (b)
  • Syriac: ܟܬܒ → kaph (k) + taw (t) + beth (b)

---

7) Lattice Integration Features

• {script_family: abjad}
• {root_structure: [C1,C2,C3]} for Semitic triliteral/quadriliteral roots
• {vowelization: absent|diacritic|mater}
• {shaping_model: simple|contextual|finals}
