Tunisian
by Waladin Ghrib
Tunisian, or Tounsi, is actually a natlang but not yet standardized or recognized, still would be a creative way to include it in here! It descends from Arabic and is roughly spoken by 13 million. This is an attempt to standardize it.

Dutesk Language
by Vorsitzenderin Sofia
Dutesk (/ˈdu.tɛsk/) was a Naiŋxic Language, historically associated with the ceremonial and maritime culture of the Tavyrop sea-cults and preserved chiefly in shoreline carvings, keel-etch records, and the Jhanuika liturgical corpus. It was characterised by heavy consonant clustering, with a permissive syllable template reaching (C)(C)(C)V(V)(C)(C), and by a stress system shaped less by lexical cadence. In careful ritual delivery, [ə] was commonly inserted as an epenthetic vowel to resolve clusters, whereas command speech more often suppresses vocalic material. Its consonant inventory is dense and fricative-rich, including /x ɣ ʃ ʒ t͡s d͡z t͡ʃ d͡ʒ ʔ/. Its vowel system is comparatively compact, conventionally analysed as /i e æ a ɨ ə o u/. Morphosyntactically, Dutesk combined templatic verbal complexes with classifier-like prefixation and suffixal case marking, and permited flexible constituent order under strong pragmatic conditioning.

Kedusiyn Language
by Vorsitzenderin Sofia
Kedusyn (/kʰɛdʊsɨn/), or Kedusiyn, also known as asiMuqvi (/ə̆sɨmʷɯqᵛɨ/), is an Aruanian language spoken by the Muk'uvi people in the north-eastern lowlands of Muqoñja Island. Its relationship with Neruañ is heavily debated, if there is any relationship it has been obscured by separation, conflict, and long periods of post-divergence contact. Unlike Neruañ, Kedusyn preserves several presumed Proto-Aruanian features, including aspirated stops /pʰ tʰ kʰ/, /ɣ/, and affricates /t͡s d͡z t͡ʃ d͡ʒ/. Ordinary clauses are mainly SVO, with a dedicated S–V–IO–DO pattern, while older head-final structures survive in conservative registers. Nouns mark three genders, and time reference is mostly analytic or contextual rather than fully inflectional. Its conservative block script masks heavy vowel-colour harmony, inherent-vowel pressure, epenthesis, breathy voice, and register-based allophony, giving spoken Kedusyn its unstable, broken cadence.

Tēsu-Jar Language
by Vorsitzenderin Sofia
Tēsu-Jar (/teːsu dʒaɹ/) is a Tesian language of the Durimic, or Northern Navari, branch, representing the continuation of older liturgical and vernacular Tesian varieties. It has a predominantly (C)V(C) syllable structure and regular penultimate stress, with productive epenthesis, usually [ə], in the repair of illicit clusters and the smoothing of phonotactic transitions. Its consonant system includes a stable retroflex series /ʈ ɖ ʂ ʐ ɳ/ and a comparatively rich fricative inventory including /x ɣ/, while the vowel system of the traditional standard is commonly analysed as /i y e ɛ a ɨ o u/. The lexicon is generally described as nontonal, although limited high-low pitch alternation is reported in formal recitation. Morphosyntactically, Tēsu-Jar is moderately agglutinative and predominantly suffixing, with basic SOV constituent order, ergative-absolutive alignment in nominals, absolutive-indexing verbal agreement, six productive cases, and strongly head-final clause structure.

Naikaumi Language
by Vorsitzenderin Sofia
Naikaumi (/nai̯.ka.u.mi/) is a Naiŋxic language and the principal surviving representative of the Kaumi branch, occupying a central place in the modern family. It is predominantly analytic and characteristically OSV, with a moderately permissive syllable template of up to (C)(C)V(C)(C)(C). Its phonology comprises 11 consonant phonemes and 8 vowel nuclei: four monomoraic vowels /a i o u/ and four contour nuclei /oi oa ui ja/. Only monomoraic vowels bear a binary High-Low register contrast; contour nuclei are toneless. Mora count is relevant for rhythm and phonotactics, but does not correspond straightforwardly to length. Its script is a featural two-tier segmental system: consonants align to a horizontal baseline, while vowels are written above it as contour curves encoding nucleus type and moraic shape; clusters are often ligatured, and rapid writing may reduce or omit vowel curves.
