// morphology-akk.el - Akkadian morphology for the NLG engine.
// 𒀭𒂗𒍪 Akkadian (akkadû), the language of Babylon and Assyria.
//
// Implements Old Babylonian Akkadian verb conjugation (G-stem / Grundstamm),
// noun declension with mimation, and noun-phrase construction.
//
// Akkadian is the oldest attested Semitic language (ca. 2800100 BCE).
// It uses cuneiform script; we work in standard Latin transliteration
// (Old Babylonian dialect the classical prestige form).
//
// Language profile:
// code=akk, name=Akkadian, morph_type=semitic, word_order=VSO/SOV,
// script=cuneiform (transliterated), family=semitic/east-semitic
//
// Key grammatical facts:
// - Semitic trilateral root system: words built from 3-consonant roots
// by inserting vowel patterns (e.g. root p-r-s iparras "he decides")
// - Grammatical gender: masculine / feminine (no neuter)
// - Cases: nominative (-um), accusative (-am), genitive (-im) "mimation"
// - Number: singular / plural (dual is vestigial in verbs)
// - Verb stems: G (basic), D (intensive), Š (causative), N (passive);
// this file implements G-stem throughout
// - Two main tense/aspect systems:
// Present-future (iparras pattern): action in progress or future
// Perfect (iptaras pattern): completed action with present relevance
// Stative (paris pattern): resultant state, often adjectival
// - No definite or indefinite article; case endings convey
// determination contextually
// - Copula: bašû (to exist/be)
//
// Verb conjugation conventions:
// person: "first" | "second" | "third"
// gender: "m" | "f"
// number: "singular" | "plural"
// tense: "present" | "perfect" | "stative"
//
// Noun declension conventions:
// gram_case: "nom" | "acc" | "gen"
// number: "singular" | "plural"
// gender: "m" | "f" (passed to akk_decline for gender-specific forms)
//
// Verbs covered (G-stem infinitive, transliterated):
// "bašû" to exist / be (copula)
// "alāku" to go
// "amāru" to see
// "qabû" to say
// "epēšu" to do / make
//
// Nouns covered with known mimation forms:
// "šarrum" king
// "awīlum" man / person
// "bītum" house
// "ilum" god
//
// Depends on: morphology.el (str_eq, str_len, str_slice, str_ends_with)
// String helpers

}

}
// Slot index
//
// Maps person × number to a 0-based slot for table lookups.
// Akkadian verb agreement does not distinguish gender in 1st person,
// and the 2nd person often conflates masc/fem in some paradigms.
// We use a 6-cell paradigm matching the most common OB presentation:
//
// 0 = 1sg (I)
// 1 = 2sg (you sg)
// 2 = 3sg m (he)
// 3 = 3sg f (she)
// 4 = 1pl (we)
// 5 = 3pl (they)
//
// Note: 2pl is rare / vestigial in attested OB texts; omitted here.
