Otterrai

Otterrai is a constructed language created for the Otterai, a semi-aquatic humanoid culture in the fictional world of Marea. It is presented as the ancestral tongue of the Otterai, used in rituals, storytelling, and daily communication. In the world-building context, Otterrai is often studied by linguists and enthusiasts.

Otterrai is largely analytic with some agglutinative suffixes marking tense and aspect. The canonical word order is subject–verb–object. Nouns take post-nominal particles to indicate number and definiteness, while verbs carry agreement markers and mood or aspect particles. The language features serial verb constructions common in riverine communities and tends toward clear modal markers in discourse.

Phonology includes five vowels (a, e, i, o, u) with length contrasts in some dialects, and consonants such as p, b, t, d, k, g, m, n, l, r, s, f, h, and a glottal stop. Otterrai allows consonant clusters in onsets but favors open syllables in most dialects. There is no phonemic tone in the standard form, though some regional varieties exhibit pitch variation for emphasis.

Otterrai uses a reed-inspired syllabary called Flumen, with signs for syllables and a limited set of logograms for core concepts. Writing is traditionally practiced on wood, parchment, or clay, with modern communities adopting horizontal text and digital forms.

Earliest inscriptions are dated to Marea’s late Bronze Age in river delta regions. There are four major dialects—Northern River, Delta Coast, Inland Plateau, and Sea Belt. They share a core grammar and lexicon but differ in phonology and vocabulary, while maintaining a high degree of mutual intelligibility among Otterai communities in the setting.
