Usaldasn

Usaldasn is a term used in the study of constructed languages to denote a hypothetical suffix that encodes multiple nominal categories in a single morpheme. In conlang grammars, it is described as a compact device for signaling definiteness, plurality, and evidentiality on nouns and noun phrases.

Etymology: The term is drawn from in-universe roots in the Usaldan lexicon; no real-world cognates exist. It is a descriptive label rather than a functional root meaning.

Phonology and orthography: The standard form is the suffix -usaldasn, realized as [u-sal-dasn] after vowels; in consonant clusters, the form may reduce to -lasn or -dasn as allomorphs.

Morphology and syntax: As a suffix, it attaches to nouns, adjectives, and proper names in the noun phrase. It is compatible with typical Usaldan case marking; the presence of usaldasn may alter determiner selection and agreement with verbs.

Usage: In world-building texts and theoretical grammars, usaldasn is used to illustrate how a language can convey multiple levels of information succinctly. It appears mainly in constructed-language discussions and fictional dialogues, rather than in natural languages.
