"Sentence Complexity in Academic Written English" is a scholarly book that focuses on the analysis of academic English. It offers a comprehensive examination of syntactic structures and sentence complexity in academic texts observed over a period of about a century. The author, Marcela Malá, analyzes texts from the fields of psychology and economics, going beyond the common research that often concentrates on selective syntactic aspects. Instead, continuous text passages are examined, categorizing each explicitly expressed finite and non-finite predication. This detailed analysis and diachronic perspective allow for the identification of recognizable trends in the expression of current academic English that may go unnoticed if research is only focused on specific topics. The book is primarily aimed at professionals and students of linguistics, but is also of interest to anyone engaged with academic English, language change, and corpus linguistics.
