The Surigaonon Alphabet

Surigaonon is a Visayan Austronesian language ^[1] spoken primarily in Surigao del Norte and Surigao del Sur — the two provinces at the northeastern tip of Mindanao, Philippines. It is also spoken on the offshore islands of Siargao, Dinagat, and adjacent smaller islands. With approximately 600,000 speakers, it is the dominant vernacular of the Caraga administrative region and serves as a lingua franca for daily communication across the Surigao provinces.

Also known as Surigawnon, the language is closely related to Cebuano (Bisaya), the most widely spoken Visayan language. Surigaonon speakers typically also understand Cebuano, and the two languages share a large portion of their core vocabulary. Surigaonon is used in everyday life, local commerce, community events, and increasingly in education as part of the Philippines' Mother Tongue-Based Multilingual Education programme.

Surigaonon uses the Latin alphabet ^[1] with a core inventory of 20 units: 5 vowels (A, E, I, O, U), 14 consonants (B, D, G, H, K, L, M, N, P, R, S, T, W, Y), and the Ng digraph which counts as a single letter. This Latin orthography was established during the Spanish colonial period and standardised further during American administration of the Philippines.

The Ng digraph is a distinctive feature of Surigaonon and other Philippine languages. Unlike in English, Ng can appear at the very beginning of a word — for example, ngalan (name) — representing the velar nasal sound. This can be surprising for speakers of European languages who are accustomed to Ng only appearing in word-final or medial positions.

Surigaonon belongs to the Visayan branch of the Austronesian language family ^[2]. The Visayan (or Bisayan) languages are a large subgroup of Philippine languages including Cebuano, Hiligaynon, Waray-Waray, Tausug, and many others. Surigaonon is specifically classified within the Eastern Visayan subgroup, which covers the languages of eastern Visayas and northeastern Mindanao.

The Austronesian language family is one of the world's largest, spoken from Madagascar in the west to Easter Island in the east. Philippine languages form part of the Malayo-Polynesian branch of Austronesian. Surigaonon shares characteristic Philippine grammatical features including the focus system, verb-initial word order, and a rich system of ligatures and enclitics.

Surigaonon has a phonological system ^[1] typical of Visayan languages: 5 vowels (a, e, i, o, u) and 15 consonant phonemes including the velar nasal represented by Ng. The language allows consonant clusters in some positions and permits closed syllables (syllables ending in a consonant), giving it a more complex syllable structure than Polynesian languages.

A key feature of Surigaonon phonology is the phonemic glottal stop, which can appear between vowels and at word boundaries. While not always written in informal contexts, the glottal stop distinguishes word meanings. Stress in Surigaonon is phonemic, and the placement of stress can differentiate otherwise identical words — a feature shared with most Philippine languages.

Surigaonon and Cebuano (also called Bisaya) are closely related Visayan languages ^[2] with a high degree of mutual intelligibility. Most Surigaonon speakers can understand and speak Cebuano, which is the dominant language of education and media in Mindanao and the Visayas. The two languages share a large portion of core vocabulary, basic grammatical structures, and phonological patterns.

Despite their similarity, Surigaonon maintains its own distinct identity with regional vocabulary, intonation patterns, and cultural expressions specific to the Surigao provinces. The language reflects the unique history of the Surigao region — including its maritime heritage as a gateway between the Visayas and Mindanao, and its rich tradition of oral literature and cultural festivals such as the Bonok-Bonok festival of Surigao City.

Surigaonon is used as a medium of instruction in the early grades of primary school in the Surigao provinces ^[1] under the Philippines' Mother Tongue-Based Multilingual Education (MTB-MLE) policy, introduced in 2012. This policy requires that children be taught in their mother tongue from kindergarten through Grade 3 before transitioning to Filipino and English as the languages of instruction.

The MTB-MLE programme has prompted the development of Surigaonon learning materials, primers, and educational resources that support literacy in the language. While Cebuano and Filipino remain the languages of higher education and official communication, the MTB-MLE policy has raised the profile of Surigaonon as a valued and formally recognised language of the Caraga region.
