Tongan

Tongan (lea fakatonga) is a Polynesian language of the Tongic branch (sister to the extinct Niuafoʻou language), the official language of the Kingdom of Tonga (alongside English), with ~187K speakers in Tonga plus diaspora communities in New Zealand (~30K), Australia (~25K), USA (~50K, especially Utah and California). Tonga is notable as one of the few Pacific nations never fully colonized — though under British protection 1900-1970, it retained its monarchy and never had European settlement on the scale of Hawaiʻi or New Zealand. Linguistically distinctive for ergative-absolutive case alignment — a hallmark of Western (Nuclear) Polynesian languages such as Samoan, Niuean and Tuvaluan, whereas only Eastern Polynesian (Hawaiian, Māori, Tahitian) is accusative — and a definitive vs. non-definitive accent system. Latin orthography developed by 1830s Wesleyan missionaries; uses ʻokina (glottal stop) and macron for vowel length. Rich oral tradition (faiva, "performance art") encompassing oratory, dance (such as the kailao war dance), and chant; the lakalaka standing dance is on the UNESCO Intangible Cultural Heritage list since 2008.
