Common questions about Mocha
What linguistic data does this West Central Oromo page show?
Word order, pitch accent, gender count, case marking, adposition direction, syllable structure, consonant inventory traits (ejectives), vowel system, morphological alignment, script, register stratification, speaker count, and geographic area. Each row is one feature with this Oromo dialect's value visible; you can add other languages to read the same feature side by side.
Where do the data points come from?
Typological features are merged from URIEL+ (Mortensen et al.) and a curated set authored against descriptive grammars. Speaker counts come from Ethnologue and Glottolog. Geographic area is computed from the Asher 2007 world language atlas. Similarity scores combine genetic distance, typological overlap, and lexical-borrowing data.
What's the difference between gaz and orm?
ISO 639-3 splits Oromo into multiple codes: gaz (West Central), hae (Eastern), gax (Borana-Arsi-Guji), ssn (Waata), and a few others. orm is the macrolanguage code covering all of them. Speakers of the major dialects can generally understand each other; the codes reflect linguistic and demographic distinctions rather than mutual unintelligibility.
Why is Oromo SOV when Semitic neighbors aren't?
Cushitic languages (including Oromo, Somali, Sidamo) have been SOV for as far back as historical reconstruction goes. Amharic — the Ethio-Semitic neighbor — adopted SOV order under Cushitic substrate influence, not the other way around. Oromo's SOV order is its inherited Cushitic-Afro-Asiatic structure.
Why does West Central Oromo cluster with other Cushitic languages?
Cushitic languages share SOV order, two-gender systems, agglutinative morphology, and basic-word cognates inherited from Proto-Cushitic. Oromo dialects sit closer to each other than any does to Somali or other Cushitic relatives. The factor breakdown chip on the row tells you which dimensions contributed most.
