+# Sudanese Arabic Machine Translation Benchmark
+
+## Dataset Description
+
+This benchmark addresses a **documented gap** in Arabic NLP research: the exclusion of Sudanese Arabic from dialectal machine translation evaluation.
+
+Recent research (Alabdullah et al., 2025) states:
+> "The focus on three dialects (Levantine, Gulf, Egyptian) constrained generalization, leaving the proposed translation techniques **untested on varieties such as Maghrebi and Sudanese Arabic**."
+
+This dataset provides the first benchmark specifically designed for evaluating Sudanese Arabic → English translation quality.
+
+## Supported Tasks
+
+- **Translation**: Sudanese Arabic → English
+- **Dialect Identification**: Can be used to test if models distinguish Sudanese from other Arabic dialects
+- **Error Analysis**: Annotated for linguistic challenges unique to Sudanese
+
+## Languages
+
+- **Source**: Arabic (Sudanese dialect)
+- **Target**: English
+
+## Dataset Structure
+
+### Data Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| id | string | Unique identifier (sud_mt_XX) |
+| source | string | Sudanese Arabic text |
+| reference | string | English reference translation |
+| difficulty | string | easy/medium/hard |
+| notes | string | Linguistic annotation |
+| dialect_markers | list | Sudanese-specific features present |
+| confusion_risk | string | Potential for dialect confusion |
+
+### Data Splits
+
+- **test**: 20 sentences (10 Sudanese Arabic + 10 MSA control)
+
+## Linguistic Features
+
+### Unique Sudanese Features
+
+| Feature | Arabic | Meaning | MT Impact |
+|---------|--------|---------|-----------|
+| يا زول | ya zol | "hey man" | High - unique vocative |
+| حي- | hay- | future prefix | High - unique morphology |
+| يتعرس | yit'arris | gets married | High - unique verb |
+| حتة | hita | room | Medium - context-dependent |
+
+### Features Shared with Egyptian (Confusion Risk)
+
+| Feature | Shared Meaning | Confusion Potential |
+|---------|----------------|---------------------|
+| دي | "this" | High |
+| عايز | "want" | High |
+| مش | "not" | Medium |
