But an Assertory sentence, proposition, or predication, is the unit with which Logic concerns itself-a sentence in which a subject is named and something is said or predicated about it.
"Logic, Inductive and Deductive"
William Minto
But while both species may not be implemented in some cases till the far distant future, some of an Assertory nature may be performed at the time when they are sworn.
"The Ordinance of Covenanting"
John Cunningham
