Marsiin

Marsiin is a fictional constructed language created for science fiction and fantasy settings. It functions as the native tongue of the inhabitants of the Marsiin region within an imagined world, and is used as a narrative and world-building element. The language is designed to be agglutinative, attaching multiple affixes to a stem to express grammatical relations, aspect, mood, and evidential stance. The typical sentence structure is subject–object–verb (SOV). Noun phrases feature adjectives and relative clauses that precede the noun, while case and agreement are expressed primarily through suffixes on nouns and verbs. Verbal morphology includes suffixes marking tense, aspect, mood, and voice, with evidential markers indicating source of information.

Phonology features a vowel inventory of five phonemes and a modest set of consonants including p, t, k, m, n, s, l, r, and h. The language makes relatively simple syllable structures, generally CV or CVC, and stresses the penultimate syllable. The writing system, Marsa script, is an alphabetic script with distinct symbols for consonants and vowels; many users also render Marsiin orthography in a Latin transcription for ease of use.

Origins and use: Marsiin emerged within online conlang and world-building communities in the 2010s, with ongoing development through grammars, dictionaries, and sample texts created by fans. It is primarily used in fictional materials, games, and role-playing campaigns associated with the Marsiin setting. There are no native speakers, and the language exists as part of a broader fictional universe.
