 A number of indexes – covering the spheres of vocabulary richness, narrative speed, and cohesion – have shown that Piper’s writing is very dynamic, as verbs prevail by far over adjectives.On the other hand, discrepancies were found in the domain of lexical richness, where chapters 4 and 14 manifest lower figures than the others; this may be due to their character, or to a pause Piper might have taken in writing.This corresponds to the fact that chapter 14 abounds in long, technical expressions, which tend to be repeated throughout this portion of the text.
