# Orthography evidence and limits
Modern writing conventions must be distinguished from older spoken languages. The social post explicitly discusses an “ancient written language”; do not substitute a claim that it explicitly says spoken languages were invented recently. Modern standardization and outside linguist contributions are real; a single exact adoption year for all present conventions was not established.

Musqueam says it formally adopted North American Phonetic Alphabet symbols, and explains ejective/glottalized consonants, lip rounding and glottal stops. https://www.musqueam.bc.ca/departments/community-services/language/

Global News (April 30, 2021) quotes language specialist Aaron Williams explaining 7 as a glottal stop. https://globalnews.ca/news/7825465/squamish-language-signs/

Kuipers, The Squamish Language (1967), preface pp. 9–10: fieldwork in 1951–54 and 1956; named speakers Isaac Jacob, Alex Peters and Louis Miranda. Evidence of earlier documentation and speaker contributions, not an adoption date for today's orthography. https://api.pageplace.de/preview/DT0400.9783111358024_A30486225/preview-9783111358024_A30486225.pdf

The research pass could not verify 1973 as the Squamish orthography's adoption year; that date is not published as fact. Nation-page extraction was available although a later Squamish direct fetch returned 403. UBC FNEL was blocked; no claims rely on its unread content.
