The Tahitian Alphabet

Tahitian (reo Tahiti) is the Polynesian language ^[1] of Tahiti and the Society Islands group, the main island cluster of French Polynesia — an overseas collectivity of France in the central South Pacific. With approximately 68,000 speakers, Tahitian is the dominant indigenous language of French Polynesia and serves as a lingua franca among speakers of other Polynesian languages within the territory, including Tuamotuan and Mangarevan.

French Polynesia comprises 118 islands spread across an area of the Pacific comparable in size to western Europe. Beyond the Society Islands (including Tahiti, Moorea, Bora Bora, and Raiatea), Tahitian is widely understood throughout the territory. Tahitian is co-official alongside French in French Polynesia, used in local government, Radio Polynésie broadcasts, education, and religious services — particularly in the Maohi Protestant Church, which uses a Tahitian-language Bible.

The Tahitian alphabet uses Latin script ^[1] with just 13 core letters: 5 vowels (A, E, I, O, U) and 8 consonants (F, H, M, N, P, R, T, V). This is one of the smallest alphabet inventories of any natural language. In addition to these 13 letters, Tahitian orthography includes the ʻeta (glottal stop, written as ʻ) and macron vowels (Ā, Ē, Ī, Ō, Ū) to represent long vowels.

The Latin orthography for Tahitian was developed by Protestant missionaries, particularly the London Missionary Society, in the early 19th century. The first Tahitian Bible was published in 1838, establishing a written standard for the language. Historically, vowel length and the glottal stop were sometimes omitted in writing, but modern standardised orthography includes them as essential phonemic distinctions — omitting them would be like omitting consonants from English.

Tahitian belongs to the Tahitic branch of the Polynesian language family ^[2], itself part of the vast Austronesian family. The Tahitic languages include Tahitian, Cook Islands Maori (Rarotongan), Tuamotuan, Penrhyn, Mangarevan, and — most notably — New Zealand Maori. Tahitian and Maori share a substantial portion of their vocabulary, reflecting their common descent from a Proto-Tahitic ancestor spoken roughly 1,500 years ago.

More broadly, Tahitian is related to all Polynesian languages — Hawaiian, Samoan, Tongan, Tuvaluan, Tokelauan, and Rapanui (Easter Island) — which together descend from Proto-Polynesian, spoken around 3,000 years ago. The Polynesian languages are among the most geographically widespread language family in the world, spread by the remarkable seafaring ancestors of today's Pacific peoples across the vast Polynesian Triangle from Hawaii to New Zealand to Easter Island.

The ʻeta is the Tahitian name for the glottal stop — the brief closure of the vocal tract that produces the catch in the throat heard in the middle of the English expression "uh-oh". In Tahitian, the glottal stop is a full phoneme ^[1] that can distinguish word meanings: for example, raa (sun) versus raʻa (sacred) are different words.

The ʻeta is written with a turned comma character (ʻ) — sometimes called the ʻokina in Hawaiian — placed before the vowel that follows the glottal stop. It is important to use the correct character (Unicode U+02BB) rather than a standard apostrophe or quotation mark, as these are punctuation marks, not phonemic letters. In informal writing, the ʻeta is sometimes omitted, which can cause ambiguity. Modern Tahitian orthographic standards require its inclusion in all formal and educational texts.

Tahitian is central to the cultural identity of the Maohi people ^[1] of French Polynesia. The language is the vehicle of a rich oral tradition including legends (orero), chants, and the celebrated tradition of Tahitian dance — the ori Tahiti — which features intricate hip movements that tell stories through movement. The annual Heiva i Tahiti festival, held every July, celebrates Maohi culture through competitive dancing, singing, and traditional sports.

Tahitian is the language of the Maohi Protestant Church, which has a long history in French Polynesia dating back to the London Missionary Society of 1797. The Tahitian Bible (Te Bibilia Tabu) remains an important cultural and linguistic reference. Despite the dominance of French in formal education, commerce, and government, Tahitian maintains a strong presence in everyday community life, inter-island radio broadcasts, local music, and the growing movement for cultural revitalisation and greater autonomy for French Polynesia.

Tahitian has one of the simplest phonological systems ^[1] of any natural language. It has only 5 vowels (a, e, i, o, u) and 8 consonants (f, h, m, n, p, r, t, v), plus the glottal stop. Like other Polynesian languages, Tahitian permits only open syllables: every syllable is either a single vowel (V) or a consonant followed by a vowel (CV). There are no consonant clusters and no syllables ending in a consonant.

Vowel length is phonemic in Tahitian — long vowels (written with macrons: ā, ē, ī, ō, ū) are held approximately twice as long as short vowels and can distinguish word meanings. Sequences of different vowels are extremely common in Tahitian — for example maeva (welcome), noanoa (fragrant) — and each vowel in such sequences is pronounced as a distinct syllable rather than as a diphthong. Stress in Tahitian falls on the second-to-last syllable (penultimate) as a general rule.
