deiiyor

Deiiyor is a fictional language created for use in speculative fiction and constructed-language communities. It is not spoken in the real world; rather, it has been described in fan wikis and language-creation discussions as an illustrative example of certain linguistic features. The term deiiyor sometimes appears as the name of the language in works that also feature its speakers, who are depicted as inhabitants of a coastal archipelago.

Origins and status: Deiiyor was conceived as part of a hypothetical language project intended to explore how phonology, morphology, and syntax interact in a conlang. In most depictions, it is presented as a member of a broader language family within the fictional world, with its own historical development and contact with neighboring languages. Scholarly-style discussions about deiiyor often focus on illustrating how imagined features might function in practice.

Phonology and grammar: The language is described as having a moderate phoneme inventory with about five vowels and roughly twenty consonants, including aspirated stops and a small set of ejectives. Its morphology is primarily agglutinative, with noun cases and suffixal markers for number, definiteness, and evidential mood. Verbs use a system of aspectual prefixes and a final particle indicating speaker stance. Basic sentence order is subject–object–verb, with marked topicalization and predication.

Usage and cultural context: In the fictional setting, deiiyor speakers are associated with maritime trade and a tradition of oral storytelling. It has been used in world-building exercises by conlang communities and occasionally appears in collaborative fiction projects as a linguistics exercise, rather than as a real language.
