This book explores how experienced authors repeat word forms in three different genres: research articles, short stories and political speeches. Methods from corpus linguistics are used to elicit all the repeated word forms in each text and then the material is analysed to establish the nature of the repetitions. The analysis seeks answers to the questions: in what naming complexes are the words repeated; is the same concept evoked; is the referential type repeated; are there metaphoric, pragmatic or other shifts in the meaning of the word?
