nasiluma

Nasiluma is a neologism used in some linguistic and cultural discussions to describe a particular pattern of language change in which existing lexical items acquire new pragmatic roles while preserving their basic phonology. The term appears in theoretical debates as a label for when form remains stable but function expands, such as a noun taking on verbal or grammatical functions through reanalysis or semantic broadening.

Etymology and usage notes are sparse and the term does not have a widely accepted origin. Nasiluma is primarily encountered in niche academic writings and online glossaries rather than in standard grammar references. It is often treated as a descriptive shorthand rather than a rigorous, widely validated category.

Definition and scope are debated among scholars. In nasiluma, an element is repurposed to serve a different syntactic function or discourse role without overt phonetic change. This can resemble functional shift or grammaticalization, but nasiluma is proposed as a way to highlight certain usage dynamics that researchers believe are distinct from more established processes.

Variations within nasiluma are discussed by some researchers, including a distinction between a focused nasiluma (clear reanalysis yielding a new function) and a diffuse nasiluma (broad, informal adoption without a single, unified syntactic status). The concept is applied across fields such as sociolinguistics, cognitive linguistics, and typology to examine how communities repurpose language elements in real discourse.

Reception and critique emphasize that nasiluma remains a niche term with overlap with well-known concepts like functional shift and grammaticalization. Proponents argue it provides useful clarity for analyzing certain patterns of language change, while critics caution against proliferating terminology without clear, observable criteria.
