Tehdyyn

Tehdyyn is a fictional language created for a collaborative fantasy world. It is described as the native tongue of the Tehdyyn people, who inhabit a coastal island archipelago in the southern sea. The name is treated as a core in-world term, with various contributors offering differing etymologies and glosses within the shared setting.

Phonology and orthography: Tehdyyn features a consonant inventory including p, t, k, ʔ, s, h, m, n, l, r, and a set of sibilants and approximants that vary by dialect. The vowel system comprises five vowels: a, e, i, o, u, with occasional vowel harmony in suffixes. The language generally uses a CV or CVC syllable structure and places primary stress on the penultimate syllable in most dialects. Writing systems range from an indigenous script to an adapted Latin alphabet used in modern texts and fan materials.

Grammar and syntax: Tehdyyn is described as analytic with agglutinative tendencies. The typical basic word order is subject–object–verb (SOV), though case marking and postposed particles allow flexible phrasing. Nouns show demonstratives and numerals, while verbs encode aspect, mood, and evidentiality through affixation and clitics. Noun phrases rely on demonstratives and numbers, and pronouns distinguish inclusive and exclusive first-person plurals in some dialects.

Usage and development: The language first appeared in community glossaries and worldbuilding notes in the early 2010s. It is widely used in fan fiction, role-playing games, and learning materials within the fictional community. Ongoing collaborative projects expand the lexicon, refine phonology, and standardize grammar across texts.

Notes: Tehdyyn exists within a fictional setting and has no use outside creative works.
