Heildina

Heildina is a constructed language used in linguistic pedagogy and worldbuilding as a teaching example. It is not a real-world language and has no associated community or country.

The name is a neologism created for didactic purposes, and in many sources it is described as an agglutinative language designed to illustrate typological variation in morphology and syntax.

Phonology features a modest consonant inventory and five vowel phonemes. The language is described as not phonemically tonal, with stress typically on the penultimate syllable. It is usually written in a Latin-based alphabet with diacritics to indicate vowel quality.

Grammatically, Heildina is presented as primarily SOV with postpositions. It uses affixal morphology to mark tense, aspect, and mood, and employs noun case marking for grammatical relations. Negation commonly appears with a clitic or particle before the verb.

In educational contexts, Heildina serves as a neutral model for demonstrating agglutinative word formation, resynthesis of affixes, and the interaction of syntax with morphology. It appears in textbooks, online courses, and worldbuilding guides to help learners compare typological options.
