lidisteis

Lidisteis is a term that appears in a niche of speculative linguistics and worldbuilding. There is no single, widely accepted definition, and its meaning varies among sources.

Origin and scope: Lidisteis is a neologism used by online conlang communities to label a hypothetical grammatical feature or a cultural concept in a fictional language or universe. In linguistic discussions, it is commonly described as a small set of markers or affixes that convey speaker stance, evidentiality, or discourse relation, though exact function differs by author.

In practice: Some writers treat lidisteis as a morphosyntactic category that attaches to verbs to indicate source of information; others use it as a high-level label for a culture's communication norms, such as ritualized address or polite discourse. Because the term is informal, definitions are not standardized and may conflict across texts.

Relation and usage: The term often appears in worldbuilding guides, conlang handbooks, and fan-edited glossaries. It is sometimes discussed alongside related concepts such as evidentiality, stance, deixis, and discourse markers.
