dalluese

Dalluese is a fictional language created for the world of the Dallu universe, a setting used in speculative fiction, role-playing games, and online conlanger communities. It is presented as a fully developed language with its own phonology, morphology, and syntax, though its practical use is primarily within fictional and game contexts rather than as a natural language.

Its phonology centers on a modest inventory of consonants and five-vowel system. Consonants include p, t, k, b, d, g, f, s, z, m, n, r, l, j, and h. Vowels are a, e, i, o, u, with stress typically placed on the syllable's second-to-last. The writing system is Latin-based, employing digraphs such as ll and ch and diacritic marks to indicate stress or tone for a subset of vowels.

Grammar is described as moderately agglutinative, with nouns taking case markings via suffixes and verbs carrying tense and aspect affixes. The basic word order is subject–object–verb, adjectives generally follow nouns, and pronouns inflect for case and number. Dalluese uses definite and indefinite articles sparingly, relying on context and case markers for definiteness.

Originally developed in the early 2000s by a community of language hobbyists and fictional-world builders, Dalluese has appeared in novels, fan-fiction, and tabletop RPG materials. Several online courses and reference grammars exist, though it remains a constructed language rather than a natural community language.

The language contributes to the depth of the Dallu setting by providing cultural and linguistic texture. It has inspired conlang discussions, world-building practices, and comparison with other fictional languages, and it serves as a case study in how constructed languages are designed for narrative purposes.
