 The analysis affords a simple means of determining the meaning of a vast range of simple propositions—those portions of discourse “in which one predicate is affirmed or denied of one subject” by way of a copula such as is, or is not (System, VII: 81)—and their composition into more complex linguistic entities (Skorupski 1989: 178–92). The proposition S is P can be understood, in the case that P is a connoting term, as the claim that the object denoted by S has the attribute connoted by P. “The summit of Chimborazo is white” asserts a fact about the world—that the object denoted by the name “the summit of Chimborazo” has the attribute connoted by the name “white” (System, VII: 97). The proposition S is P, where P is a non-connoting term, can be understood as the claim that the object denoted by S is the same object as that denoted by P. “Tully is Cicero” asserts merely a fact about those names—that the name “Tully” is used to refer to the same object as the name “Cicero”.
