Unit 2: Morphophonemic Rules & Syllables
The logic of consonant assimilation and syllable structures within the Qubee script.
Technical Morphophonology
When certain sounds meet in Afaan Oromoo, they undergo mandatory transformations known as assimilation rules.
Core Assimilation Rules
- s + na: Optionally changes to -jjna. Example: ajjees + na -> ajjeejna (we kill).
- l/r + ni: The following 'n' is assimilated. Example: baal + ni -> bdalli (leaf). jir + na -> j{rra (we live).
- k/q/g + ta: The first consonant assimilates to the following. Example: beek + ta -> beetta (you know).
Syllable Structural Archetypes
Every Oromo syllable must conform to one of four specific patterns (where V is vowel, C is consonant):
- CV: la-ma (two)
- CVV: naan-noo (region)
- CVC: af-ur (four)
- CVVC: sad-deet (eight)
Important: No syllable in Oromo truly starts with a vowel; a silent glottal stop is always present at the beginning of vowel-initial words.
