On the rugged inlets of central British Columbia, a few dozen people still speak Nuxalk (also called Bella Coola). Descriptions of this Salishan language include words analysed without any vowel segment, a long-running subject of phonological research.
The textbook example, first reported by Hank Nater in his 1984 grammar, is:
xłp̓x̣ʷłtłpłłskʷc̓
"then he had had in his possession a bunchberry plant"
Read that again. There is not a single a, e, i, o, or u — not even a schwa. Yet Nuxalk speakers pronounce it as a fluent, unbroken word. Other classics include p̓x̣ʷłt ("bunchberry"), cktskʷc ("he arrived"), łxʷtłcxʷ ("you spat on me"), and even single-word sentences like sps ("northeast wind").
How is this possible? In most languages, every syllable is built around a vowel — an open, sonorous nucleus that carries the breath. Nuxalk seems to break this rule. Two main analyses have been proposed:
- Obstruents as syllabic nuclei. Nater, and before him James E. Hoard, argued that even non-sonorant consonants — stops and fricatives — can serve as the heart of a syllable in Nuxalk. The s in sps simply is the syllable.
- No syllables at all. Bagemihl's influential 1991 dissertation went further and proposed that Nuxalk words are organised not into syllables but directly into moraic timing slots, making the notion of "syllable nucleus" irrelevant.
Native speakers themselves do not perceive a "missing vowel". They do not feel they are inserting a covert schwa to make the word pronounceable — the descriptive record, from Newman's 1947 phonology to Nater's fieldwork and recordings, finds no epenthetic vowel between them. The word xłp̓x̣ʷłtłpłłskʷc̓ takes about a second to pronounce and is, to the speaker, just a word.
The implications go far beyond Nuxalk. If a language can build words from pure obstruent strings, then the universal claim that every syllable needs a vowel cannot stand in its strongest form. Phonologists now distinguish more carefully between sonority (the acoustic property) and nucleus-hood (the structural role), and Nuxalk is the example everyone teaches.
Today fewer than 20 fluent first-language speakers of Nuxalk remain, almost all elders in Bella Coola. The Nuxalk Nation runs immersion programs and a language-house initiative; recordings made by Nater in the 1970s, and more recent documentation supported by the First Peoples' Cultural Council, are racing to record a phonology unlike any other.
