 Signification contrasts with the other properties of terms in one major respect, for the other properties (perhaps with the exception of appellation in some authors, and natural supposition) are all properties of terms relative to their occurrence in particular propositions – indeed, they are properties of occurrences of  terms.[7]  Signification, however, is independent of a term's particular uses or occurrences: “Signification differs from supposition in this that signification is prior to supposition” (Lambert, tr. Maloney, p.  254).[8]  Indeed, the other properties are dependent on the signification of the term. For example, an occurrence of a term can only supposit personally (see  section 3)  for certain objects in virtue of its signifying them, among others, or signifying some property they share.
