A semantic property of general or resourcive terms by which their competent application permits legitimately unforeseen borderline cases because it is impossible, in advance, to specify every future circumstance that might bear on application; open texture is not mere vagueness from sloppy use but an intrinsic feature of language that leaves room for legitimate interpretive judgment when novel cases arise.

Principle

When a term exhibits open texture, competent users accept that some instances will require interpretation rather than being determinately settled by prior explicit criteria; this enables language to cover novel situations but creates genuine indeterminacy at a margin.

Demonstration

Illustrative scenario — Situation: A statute prohibits ‘‘vehicles’’ in a pedestrian plaza. Recognition: The term is general and was drafted without enumerating device types. Action: A city official must decide whether an unforeseen device (e.g., a small electric personal transporter) counts as a vehicle. Consequence: The official applies interpretive criteria (purpose, safety, social expectations) rather than consulting a preexisting exhaustive list, because the term’s open texture permits such judgment.

Misapplication

Mistakenly treating open texture as if it licenses arbitrary discretion or that any disagreement indicates defective language; the error is to conflate ‘‘allowing interpretive judgment in novel cases’’ with ‘‘no constraints on interpretation’’ rather than recognizing interpretive norms still apply.

Consequence

Open texture requires institutions (courts, regulators, experts) and ordinary speakers to supply context-sensitive interpretive criteria in borderline cases; it explains why doctrines of interpretation and discretionary decision-making are necessary where general terms are used.

Reversal

Open texture is absent when a term is fully specified by a non-semantic device (e.g., a formal specification, a mathematical definition, or an exhaustive statutory list); in such contexts application is determinate because the relevant features have been fixed.

Boundary

Clearly within: a statute banning ‘‘weapons’’ without definition. Boundary case: the status of an improvised tool that can be used as a weapon depends on purpose and context. Clearly outside: a technical standard that defines ‘‘ISO 9001-certified device’’ by explicit procedural criteria.

Semantic Tension

Flexibility to cover unforeseen cases ↔ Demand for precision and predictability; open texture trades off some predictability for linguistic adaptability.

Synthesis

Open texture is a structural feature of general language that makes interpretation an unavoidable part of application: it is the source of legitimate indeterminacy at margins and the reason interpretive norms and institutional judgment must supplement general terms.
