Tēsu-Arar Language

Tēsu-Arar is a Tesian language of the Durimic (Northern Navari) family, spoken across the Haraz Basin and much of the central Deresmar plains, with Duric Tēsu-Arar serving as the best-described standard derived from the Classical register. Phonologically, the language is conservative, preserving a stable retroflex series /ʈ ɖ ʂ ʐ ṇ/ and a five-vowel system /i e a o u/, alongside the approximants /w/ and /j/. Syllable structure is predominantly (C)V(C), with productive epenthesis, typically [ə], and predictable penultimate stress; the lexicon is nontonal, though limited high-low pitch alternation appears in formal recitation. Morphosyntactically, Tēsu-Arar is moderately agglutinative and predominantly suffixing, with basic SOV order, ergative-absolutive alignment on nominals, absolutive-indexing verbal agreement, six productive cases, and strongly head-final clause structure.
