 Later, however, ‘supposition’ came to replace ‘appellation’, and the latter term underwent its own transformation. Supposition became the leading property of an occurrence of a term in a proposition (including now predicates, and even parts of predicates), distinguishing what in particular was being spoken of on some occasion of utterance by some particular use of a word, from that word's general property of meaning (signification). The term ‘man’ signifies the form of man wherever the term occurs, but each occurrence of the term ‘man’ supposits for the individuals in possibly distinct classes or groups of men (note that it supposits for the men, not the classes).
