// 𐎀𐎎𐎗𐎚 — Ugaritic, the language of the city-state of Ugarit.
|
||||
//
|
||||
// Implements Ugaritic verb conjugation (G-stem, suffix and prefix conjugations),
|
||||
// noun declension (three cases, gender, number, dual), and noun-phrase construction.
|
||||
//
|
||||
// Ugaritic is a Northwest Semitic language (ca. 1400–1200 BCE), written in a
|
||||
// 30-character alphabetic cuneiform. It is closely related to Biblical Hebrew
|
||||
// and Phoenician. We work in standard Latin transliteration:
|
||||
// ʼ = aleph (glottal stop) ʻ = ʿayin ḫ = het ġ = ghayin
|
||||
// ṯ = thet ẓ = emphatic z š = shin ṣ = tsade
|
||||
//
|
||||
// Language profile:
|
||||
// code=uga, name=Ugaritic, morph_type=semitic, word_order=VSO,
|
||||
// script=alphabetic cuneiform (transliterated), family=semitic/northwest-semitic
|
||||
//
|
||||
// Key grammatical facts:
|
||||
// - Semitic trilateral root system (nearly identical to Hebrew/Arabic)
|
||||
// - Grammatical gender: masculine / feminine
|
||||
// - Cases: nominative (-u), accusative (-a), genitive (-i)
|
||||
// (mirrors Akkadian but with shorter endings — no mimation in Ugaritic)
|
||||
// - Number: singular / plural / dual
|
||||
// - Dual: nom -āma, gen/acc -ēma
|
||||
// - Verb tenses:
|
||||
// qtl (perfect, suffix conjugation) — completed action
|
||||
// yqtl (imperfect, prefix conjugation) — ongoing / future action
|
||||
// - Verb stems: G, D, Š, N (this file: G-stem throughout)
|
||||
// - No separate definite article (unlike later Hebrew ha-)
|
||||
// - Copula: root kn (to be)
|
||||
//
|
||||
// Verb conjugation conventions:
|
||||
// person: "first" | "second" | "third"
|
||||
// gender: "m" | "f"
|
||||
// number: "singular" | "plural"
|
||||
// tense: "perfect" | "imperfect"
|
||||
//
|
||||
// Noun declension conventions:
|
||||
// gram_case: "nom" | "acc" | "gen"
|
||||
// number: "singular" | "plural" | "dual"
