speech the article, adverb, preposition, and conjunction can never be
anything but syncategorematic, while the interjection is
acategorematic, like the vocative case of nouns and the imperative and
optative moods of verbs, which do not enter at all into the form of
sentence known as the proposition.].

72. Categorematic literally means 'predicable.' 'Horse,' 'swift,'
'galloping' are categorematic. Thus we can say, 'The horse is swift,'
or 'The horse is galloping.' Each of these words forms a term by
itself, but 'over' and 'swiftly' can only help to form a term, as in
the proposition, 'The horse is galloping swiftly over the plain.'

73. A term then may be said to be a categorematic word or collection
of words, that is to say, one which can be used by itself as a
predicate.

74. To entitle a word or collection of words to be called a term, it
is not necessary that it should be capable of standing by itself as a
subject. Many terms which can be used as predicates are incapable of
being used as subjects: but every term which can be used as a subject
(with the doubtful exception of proper names) can be used also as a
predicate. The attributives 'swift' and 'galloping' are terms, quite
as much as the subject 'horse,' but they cannot themselves be used as
subjects.

75. When an attributive appears to be used as a subject, it is owing
to a grammatical ellipse. Thus in Latin we say 'Boni sapientes sunt,'
and in English 'The good are wise,' because it is sufficiently
declared by the inflexional form in the one case, and by the usage of
the language in the other, that men are signified. It is an accident
