Deixase

Deixase is a term that appears only rarely in linguistic discussions and is not widely adopted as a standard label in the field. In the limited contexts where it has been used, deixase refers to a hypothetical component or process that identifies and resolves deictic reference in discourse, effectively acting as an element that locates words such as this, that, here, and now relative to a speaker or reference context. The term is not part of the formal taxonomies of deixis and is often described as speculative or experimental.

Etymology and interpretation are informal. The form deixase suggests a blend of deixis, the established concept describing context-dependent reference, with the -ase suffix commonly used in naming functional agents (as in enzyme names). However, there is no standardized definition or cross-linguistic validation for deixase, and most discussions treat it as an auxiliary or hypothetical construct rather than a fixed category.

In usage, deixase is typically mentioned in theoretical or methodological discussions about how deictic anchoring might be modeled, whether in psycholinguistics, cognitive linguistics, or computational linguistics. It is sometimes invoked to illustrate the idea of a dedicated processing unit or module responsible for deictic centroid determination, without asserting its existence as a concrete mechanism.

Because deixase is not a widely recognized term, most scholarly work on deictic expressions continues to use the established terminology of deixis, deictic center, and deictic expressions. Related concepts include deixis, deictic center, deictic shift, and anaphora.
