singular proposition

In logic, a singular proposition is a statement where the subject is a proper name or a descriptive phrase that uniquely identifies an individual. This is distinct from other types of propositions, such as categorical propositions, which can refer to all or part of a subject class.12

A proposition itself is an idea that serves as a basis for an argument or investigation. Simple propositions are those that cannot be broken down into separate statements. Propositional functions, on the other hand, are statements with variables that become true or false once specific values are assigned to those variables.345
