Leostumises

Leostumises is a term used in speculative linguistics to describe a pattern of semantic extension in which a single lexical item gains new related meanings through iterative metaphorical reanalysis across a speech community, producing stable, layered senses. The phenomenon is most often discussed in studies of constructed languages or thought experiments about language change, where social propagation helps lock in extended senses while the original sense remains productive in certain domains.

Origin and reception: The term is a neologism dating from the early 21st century, coined by proponents of conlang-based methodology. It is not part of mainstream linguistics and has limited adoption outside speculative or hobbyist circles.

Characteristics: Leostumises involves cross-domain semantic shift, social diffusion, and reanalysis of form to accommodate new meanings. The base word typically remains central in its phonological form, supporting continuity across senses and communities.

Examples: In a case study language used for a conlang project, the word for "seed" gradually acquires senses such as "potential," "start," and "opportunity," while preserving agricultural usage in farming contexts. In another example, a term for "light" extends to "clarity" and "insight" through repeated metaphorical extension across domains and generations.

Relation to other ideas: Leostumises overlaps with semantic broadening and semantic shift but emphasizes social propagation and cross-domain reanalysis. It is related to lexical diffusion and core conceptual metaphor, while remaining distinct in its emphasis on stable, layered extensions across a community.
