To interrupt the stream of vowels is profound, is violent, repressive, and necessary. Glottal stops like “k” and “t” sever the breath, tighten the belly, clench the mouth, like water crashing on walls of rock.
Hard consonants cut the emotion off, while the soft ones do not obstruct it. “N”s and “l”s are smooth like boulders the water curves around.
Diphthongs are gliding vowel sounds that gently inflect emotion, wringing it out, the way grief bends gradually into acceptance of loss.
