This chapter explores lexical repetition and its text-organizing function in French written discourse (non-narrative texts). On the basis of Patterns of lexis in text (1991) by M. Hoey, I show how an analysis of lexical relations in texts can reveal the relatedness of adjacent or non-adjacent sentences, which produce elaborate patternings, and reticulate organisations. In this way, lexial units, sentences, nets, and hypotexts constitute the units of text.
