📄 Iʿrāb, Tanwīn and Status Constructus: Some Thoughts on the History of the Nominal Declension in Semitic and Arabic

Summary

The paper asks how much of the Classical Arabic noun declension is truly inherited from Common Semitic. Arabic keeps case endings and nasal endings. This looks like Akkadian-style conservatism, but some parts may be later systematization. Stempel compares endings for the singular, dual and plural, and for the status constructus, across Akkadian, Hebrew, Syriac, Arabic and Geʿez. He then reconstructs the proto-forms and tests them against sound laws and typology.

His main claims are:

• The Arabic singular is essentially inherited.
• The Arabic dual and plural carry an extra final vowel shared with Proto-Hebrew.
• The fully case-inflected construct singular is an Arabic innovation. Originally the construct was an endingless casus indefinitus, as still seen in Akkadian and inferable for Hebrew. The likely model was a genitive pattern built with a relative pronoun.
• Nunation (tanwīn) first carried no meaning. It came to mark indefiniteness because its n-less sandhi variant was frequent in definite genitive contexts.

The work matters because it shows that apparently archaic morphology can be a reorganized system.

Key points

• Reconstructed Common Semitic paradigm:
  • Singular: nom. -um, acc. -am, gen. -im.
  • Dual: nom. -ān, oblique -ayn.
  • Two plurals: a general one (-ū/-ī) and a distributive one (-ūnu/-īni) for individual members. Akkadian šarrū means kings as a group; šarrūnu means individual kings.
• Singular and dual sound changes:
  • Arabic -un/-an/-in arise from the common change of final -m to -n.
  • Akkadian gradually lost mimation, and forms with and without it alternated freely.
  • Geʿez dual -ē continues *-ayn after losing the nasal.
• Arabic plural: -ūna/-īna is analysed as a back-formation. Once the absolute form was felt to equal the construct plus a nasal, a nasal was added to the construct forms -ū/-ī.
• Hebrew evidence for an endingless construct: dəbar-ka 'your word' can only continue a form without a case vowel. This matches the endingless Akkadian construct singular.
• Possessive models and Ethiopic:
  • The genitive pattern {noun + relative pronoun + genitive} is attested in several languages: Akkadian ša, Syriac d-, Geʿez za-, and Moroccan Arabic dyāl.
  • Egyptian Arabic uses a possession noun instead, bitāʿ.
  • Ethiopic behaves as a marginal language that preserves archaisms.
  • The PDF header gives the issue as Folia Orientalia 44, 2008.

Interesting ideas

• I1. Proportional back-formation: When one paradigm cell is felt to equal another cell plus an affix, speakers fill gaps by applying that proportion. A learner could induce such morphology relations instead of memorizing endings. — For Mova (tokens): The en lemmatizer could mine proportions like base : base+affix across paradigms to guess lemmas and forms of unseen words.
• I2. Unmarked forms where a word is not syntactically bound: Words outside government relations surface without grammatical marking, as in vocatives, the first member of compounds, and predicates. This gives a structural cue for why marking disappears. — For Mova (tree): In English noun–noun compounds the first member usually lacks plural marking. The parser could use this as a feature to separate compound modifiers from heads and to recognize vocatives.
• I3. A sandhi variant can acquire meaning by context frequency: A phonetic variant common in one construction (definite genitives) gradually becomes a marker of that construction's meaning. — For Mova (learn): When building silver data, track which surface variants cluster with which constructions, so that contractions or reduced forms are treated as possible signals rather than noise.
• I4. Group plural versus individuals plural: The paper separates a collective plural from a distributive one that counts individual members. — For Mova (world): The world model could mark plural entities as collective or distributive, which affects how quantities are summed in maths word problems.
• I5. Proper names stay conservative and inherently definite: Names resist analogical change and are definite regardless of their marking. — For Mova (frames): Coreference could treat proper names as definite anchors even without an article, and give them priority as antecedents.
