instancesuchPerson

instancesuchPerson is a placeholder identifier used in informal discussions of personhood and in logic and data-modeling examples to denote an arbitrary individual who satisfies a specified set of properties. It is not a fixed person; rather, it stands for "an instance of the class person such that ..." The naming, which resembles code-like variable syntax, signals its role as a variable or existentially quantified element in a sample predicate or description.

In formal logic, such an item would be represented as a variable x with the property Person(x) and additional constraints (for example, x is tall and x is employed). The phrase “an instance such person” describes an entity that satisfies the given properties, highlighting how descriptions depend on the predicates attached to the individual. This usage helps illustrate how complex descriptions are resolved in reasoning about identity and reference.

Context and usage: instancesuchPerson appears in ontology design, database and data-modeling tutorials, and discussions of natural language semantics. It serves as a generic example to show how to combine properties to specify a target individual without naming a real person. Different authors may use variant names such as instanceOfSuchPerson or suchPersonInstance, but the underlying idea remains the same: a representative, unspecified individual constrained by a property set.
