    • n epichirema In logic:
    • n epichirema As used by Aristotle, a reasoning based on premises generally admitted but open to doubt.
    • n epichirema As commonly used, a syllogism having the truth of one or both of its premises confirmed by a proposition annexed (called a prosyllogism), so that an abridged compound argument is formed: as, All sin is dangerous; covetousness is sin (for it is a transgression of the law); therefore, covetousness is dangerous. “For it is a transgression of the law” is a prosyllogism, confirming the proposition that “covetousness is sin.”
