casessuch

Casessuch is a fictional term used in theoretical linguistics and formal semantics to denote a construct that identifies or selects “cases” within a dataset or model that meet a specified condition. The word blends the ideas of grammatical case and a relational phrase such as “such that,” signaling a focus on instances that satisfy a given property.

Definition and formal notion: In a simplified view, casessuch represents an operator or labeling device that, given a criterion P and a domain D (for example, sentences, clauses, or tokens with case information), yields the subset of D in which the case-bearing elements satisfy P. In practice, researchers may describe casessuch as a function casessuch(P, D) or as a tagging guideline used during annotation, analysis, or parsing to isolate relevant data.

Origin and usage: The term is presented here as a stylized concept used to illustrate how researchers might discuss data selection based on case information. In theoretical work, casessuch helps clarify how different languages encode grammatical relations through case, how case-marking patterns align with semantic roles, and how parsing or typological comparisons can be structured around conditional case criteria.

Examples: In a corpus annotated with case and role labels, casessuch(Agent in nominative) would identify sentences where the agent carries nominative marking, while casessuch(Theme in accusative) might isolate sentences with accusative marking for themes. These usages are illustrative placeholders for a broader methodological idea rather than a fixed linguistic feature.
