The goal of this paper is threefold: (i) to present some practical aspects of using the full-text version of the Corpus of Historical American English (COHA), the largest diachronic multi-genre corpus of the English language, in the investigation of a linguistic trend of change; (ii) to test a widely held assumption that sentence length in written English has been steadily decreasing over the past few centuries; (iii) to point to a possible link between changes in sentence length and changes in English syntactic usage. The empirical proof of concept for (iii) is provided by the decline in the frequency of the non-finite purpose subordinator in order to . Sentence length, genre and the likelihood of occurrence of in order to are shown to be interrelated.
