The redundancy is a method which strengthens the transmitted message in language. And the redundancy has two ways: expanding syllable and explanatory repetition. Well, the repeated faulty wording is a wordiness of the sentence structure, which should be deleted. So, retaining the redundancy is a seeking for superfluity, and it attributes the success to the sufficient principle of transmitting message. Leaving the redundancy out is a seeking for simplicity, and it attributes the success to the economical principle of expression. So it is a problem of how to hold the right simplicity. Nowadays there is a tendency that the demand is too strict for the linguistic norm. Now it may begin with the distinction between the redundancy and the repeated faulty wording in two ways: one is linguistic sensation and another is how to express. But it sometimes is difficult to differentiate redundancy from repetition.
