 Not all words have connotation. Mill notes that words can be singular or general. “Cicero” is a singular name—applying to only one object, namely Cicero. “Roman” is, by contrast, a general name—applying to many objects, including Cicero but also Augustus, Nero, and many others. While “all concrete general names are connotative” (System, VII: 32)—signaling the attributes which justify our application of the name to individual objects—the same cannot be said of singular names. To be sure, some singular names are connotative—“the author of De Re Publica” is, as we would say, a definite description, and picks out one individual by way of signaling its attributes—but not all are. The name “Cicero” does not connote any attributes at all—but is a proper name, and serves simply as a marker for that individual (Schwartz  2014).[1]
