In his studies of the structure of the English language, Samuel Green, a 19th-century grammarian and educator, made extensive use of paraphrase as a descriptive device. This paper argues that in doing so, Greene anticipated some of the methods and concepts of early transformational theory — and even some of the transformations themselves. It first presents a short history of the concept “transformation”, then discusses the transformations in four of Greene’s works. Greene’s use of transformations follows plausibly from his view of language, as is shown by excerpts from the prefaces to his books. Greene’s status as a transformationalist is then reconsidered with reference to the characteristics of transformations as inferred in the early part of this paper. Comparisons with other 19th- and early 20th-century grammarians demonstrate that Greene was unusual in his concern for underlying meaning and in his use of process in linguistic description.
