The Sika Alphabet

Sika is a Central Malayo-Polynesian language ^[1] spoken primarily on Flores Island in East Nusa Tenggara Province, Indonesia. With approximately 175,000 speakers, it is centred in Sikka Regency (Kabupaten Sikka) on the eastern half of Flores. Sika is one of the larger and better-documented languages of Flores Island, which hosts an unusual concentration of distinct languages across its relatively small area.

Flores Island has been predominantly Roman Catholic since Portuguese missionaries arrived in the 16th century — the island's name comes from the Portuguese "Cabo das Flores" (Cape of Flowers). This Catholic heritage influenced the development of Sika literacy and oral literature, as missionaries used the language for religious instruction. Today, Sika is used alongside Indonesian in daily life, ceremonies, and community decision-making in Sikka Regency.

Sika uses the Latin alphabet ^[1] with 19 letters: A, B, D, E, F, G, H, I, K, L, M, N, O, P, R, S, T, U, W. This Latin orthography was established through missionary and colonial contact and continues under the Indonesian national orthographic tradition. Unlike many Philippine and some Indonesian languages, Sika does not use the Ng digraph as a core letter — its nasal consonant inventory is represented by N and M.

The Sika spelling system is relatively straightforward, with most letters representing consistent sounds. Letters such as C, G (as in "gem"), J, Q, V, X, Y, and Z are not part of the native Sika alphabet and appear only in Indonesian or international loanwords. The 19-letter inventory accurately represents the phonological system of the language, making Sika orthography accessible to speakers learning to read.

Sika belongs to the Central Malayo-Polynesian (CMP) branch of Austronesian ^[2] — a large subgroup of Austronesian that encompasses languages of the Lesser Sunda Islands (Bali to Timor), Maluku, and parts of the Pacific. Other CMP languages include Balinese, Sasak (Lombok), Tetum (Timor-Leste), the Maluku languages, and the languages of the Moluccas. All of these languages trace their ancestry to the same Proto-Austronesian source.

On Flores Island itself, Sika is one of approximately seven major language groups, including Ende, Lio, Ngada, Ngadha, Manggarai, and Bima (at the eastern tip). Despite their geographic proximity, these languages are not mutually intelligible and have developed distinct vocabularies and grammatical features. Flores's linguistic diversity reflects the island's history of relatively isolated communities developing over many centuries before large-scale contact.

Sika has a rich tradition of oral literature ^[1] including creation myths, genealogical recitations, ritual chants, and ceremonial speech forms known as "wunut" — a heightened language register used in traditional ceremonies, clan councils, and rites of passage. This ritual speech is characterised by parallelism, fixed phrases, and metaphorical vocabulary that differs substantially from everyday speech.

The oral literature of Sika reflects the community's cosmological beliefs, ancestral connections, and social organisation. Traditional ceremonies including marriage negotiations, funerals, and harvest rituals are conducted with elaborate exchanges of ritual speech that encode clan identities, obligations, and relationships. This ceremonial language is one of the most important markers of Sika cultural identity and continues to be used by community elders even as younger generations become more oriented toward Indonesian.

With approximately 175,000 speakers, Sika is considered relatively stable ^[2] compared to many smaller languages of eastern Indonesia. It has an active speaker community, is still transmitted to children in many households, and is used in ceremonies and community life. However, like all regional languages in Indonesia, it faces increasing competition from Indonesian in education, employment, and media.

Younger Sika speakers in urban areas and those with higher education tend to use Indonesian more frequently and may have lower proficiency in the traditional ceremonial register of Sika. Language documentation and revitalisation efforts by Indonesian academics, Catholic institutions, and community organisations help preserve knowledge of Sika, particularly its oral literature and cultural vocabulary. The language's relatively large speaker base gives it a stronger foundation than many smaller Flores languages.
