Emphasis Harmony in Arabic: A Critical Assessment of Feature-Geometric and Optimality-Theoretic Approaches
Bibliographic record
Abstract
This overview article examines vowel-consonant harmony, specifically emphatic harmony (also referred to as pharyngealization, velarization, or uvularization), which is found in Semitic languages. It provides a comprehensive overview of emphasis harmony in Arabic dialects from feature-geometric and optimality-theoretic perspectives. From the feature geometric account, emphatic consonants are considered as a natural class within the guttural group that has the [pharyngeal] or [RTR] ‘retracted tongue root’ feature. This view has been questioned and challenged recently by some researchers who argue for the exclusion of emphatics from the guttural group. The different arguments discussed in this paper show that researchers cannot reach a consensus regarding which consonants belong to the guttural group and which features are shared between these consonants. This paper shows that studies adopting an optimality-theoretic perspective provide a more comprehensive view of emphasis harmony and its fundamental aspects, namely, directional spreading and blocking, spread from secondary emphatic /r/ and labialization. However, this paper reaches two main conclusions. Firstly, unlike feature geometry, optimality theory can provide a clearer picture of emphasis harmony in an accurate and detailed way, which does not only clarify the process in one Arabic dialect but also describe the differences between dialects due to the merit of (re)ranking of constraints. Secondly, emphasis harmony is different from one Arabic dialect to another regarding its direction, involvement of emphatic /r/, and labialization. These differences between dialects indicate that emphasis harmony is not an absolute phenomenon.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
