/o↓ ẽ aːh/

Grammatic class
Emotional discursive marker  (discursive interjection)

Kinesthetic arc
Contraction  →  Processing  →  Sustained lament
The sequence mirrors the involuntary physiology of indignant surprise: the diaphragm contracts (o̊), the cranial resonance processes (ẽ), the voice releases and sustains the affect (āh). The body does this before any word; Uomé just encodes it.

Meaning and use
1.  Surprise indignation
Precedes a proposition whose content violates the speaker's expectations. It is functionally equivalent to the 
emotional “mas” in Portuguese, the mais in French, the ma in Italian — but with explicit phonetic, not historical, motivation.

Therapeutic and speech therapy note
The production of o̊ẽāh involves three distinct points of articulation in a controlled sequence:
·  Inversion of air flow (ingressive)  ·  Activation of nasal resonance  ·  Conscious and sustained jaw opening
Recommended as a vocal warm-up and respiratory awareness exercise. The long mora of āh promotes regulation of the diaphragm and proprioception of expiratory flow.

o̊ẽ  (adversative conjunction: more + no) + āh  (emotional opening ingressive vowel, prolonged by double mora)
The base form o̊ẽ is the adversative conjunction of Uomé. The addition of āh — a central open oral vowel, with a long mora — grammaticalizes the emotion directly in the speaking body, converting the logical contrast into embodied indignation.
