The Hawaiian Alphabet Has Only 13 Letters — and That's All It Needs

Thirteen Letters and One More

The Hawaiian alphabet consists of 13 letters: the five vowels (A, E, I, O, U) and eight consonants (H, K, L, M, N, P, W, and a character called the 'okina). The 'okina — a glottal stop represented by a reversed apostrophe — is sometimes counted separately from the alphabet's thirteen standard letters, giving Hawaiian either 13 or 14 symbols depending on the counting convention.

By comparison, English uses 26 letters, Russian 33, and some alphabets extend further still. Hawaiian's 13 letters make it one of the smallest alphabets in active use in the world. This economy is not a sign of a simple language — Hawaiian has complex grammar, rich vocabulary, and a literary tradition including oral histories, chants, and poetry of considerable sophistication. The small alphabet simply reflects a phonological system that uses a different set of sounds than most European languages.

Why Hawaiian Uses So Few Letters

Human languages vary enormously in their sound systems — the phonological inventories that speakers use to build words and sentences. English uses approximately 44 distinct sounds (phonemes), including numerous consonant clusters, dental fricatives (the "th" sounds), and vowel distinctions that many other languages lack. Hawaiian uses far fewer sounds: 8 consonant phonemes and 5 vowel phonemes, with no consonant clusters in the traditional language.

This phonological simplicity is characteristic of Polynesian languages as a group. Hawaiian, Samoan, Tongan, and Maori all share similar features: open syllables (syllables that end in vowels), simple consonant-vowel structures, and a relatively small phoneme inventory. The result is that Polynesian words tend to be longer but more pronounceable across language backgrounds than many other languages — hence the relatively accessible sound of Hawaiian place names like Honolulu, Waikiki, and Humuhumunukunukuapua'a.

The Language's Near-Death and Revival

Hawaiian was once the primary language of the Hawaiian Islands, spoken by hundreds of thousands of people. The arrival of European explorers in 1778, followed by waves of colonization, disease, and American annexation, nearly destroyed the language. By the 1970s, Hawaiian was critically endangered, with fewer than 2,000 native speakers and no children being raised speaking the language natively.

A remarkable revitalization effort began in the 1980s with the establishment of Hawaiian-language immersion schools (Pūnana Leo). Children entering these preschools at age three were taught entirely in Hawaiian, and the program gradually extended through high school and into university education. Today, Hawaiian is taught throughout the state's school system, and the number of fluent speakers has grown substantially, with estimates ranging from 18,000 to over 24,000 depending on proficiency criteria.

The 13-letter alphabet is central to that revival. It is simple enough for young learners to master quickly, consistent enough that pronunciation rules are far more regular than in English, and beautiful enough that the language's distinctive sound — all vowels and soft consonants, flowing between syllables — has proven a powerful draw for Hawaiians reconnecting with their cultural heritage.
