 Statements are composed of two types of parts: principal and secondary. The principal parts of a statement are the nouns and verbs, that is, the subjects and predicates whose properties are the focus of the first branch of terminist logic. The secondary parts are those that remain: “the adjectival name, the adverb, and conjunctions and prepositions, for they are not necessary for the statement’s being” (Kretzmann 1968, p. 13). These are words which do not have signification in themselves, but only in conjunction with other significative words, namely the subject and predicate (Kretzmann 1966, p. 24). Because these words do not have signification in themselves, they do not have any of the usual properties of terms — supposition, copulation, and ampliation. Nevertheless, they still have a significative function. Explaining this function is the focus of Sherwood’s treatise on syncategorematic terms.
