predication:謂語。語法上來說，一個句子是有一個主語和一個謂語組成的。主語：that about which sth is said is the subject. 謂語：what is said is the predicate.?

"predication" is the idea-connecting process by which we attribute sth to sth else. if predication is the process of bringing ideas together and coupling them, then the test of sound predication is that the ideas that are brought together belong together. ideas belong tegether if their grammatical connection reflects a real connection in the objective order of things.

也就是謂語要如實的反應(yīng)主語。比如：蕁麻疹是一種傳染疾病。這就是一個合理的論斷。
