Battology

Battology refers to the wearisome repetition of words in speaking or writing.

Battlogy comes from the Greek word battologia meaning "speaking stammeringly" from battos meaning "stammerer" and logia meaning "one who speaks (in a certain manner)" which entered English in 1500s.

I believe that a great writer knows how to use words so well that any readers would not even find any word repetition in his/her articles.
