A Modern English Grammar on Historical Principles, Volume 1: Otto Jespersen Collected English Writings (Otto Jespersen: Collected English Writings)

A Modern English Grammar on Historical Principles represents the magnum opus of Danish linguist Otto Jespersen, originally published in multiple volumes between 1909 and 1949. This comprehensive work moved away from the traditional, prescriptive approach to language study, which focused on enforcing rigid rules of 'correctness,' and instead championed a descriptive, historical methodology. By examining the actual evolution of English through centuries of usage, Jespersen provided a structural framework that became a cornerstone of modern linguistic science.

The 2006 Routledge edition serves as a critical scholarly resource, reissuing Jespersen’s foundational research for contemporary students and academics. Jespersen’s design was to trace the development of linguistic forms through their functional roots, viewing language as a living, organic entity shaped by psychological and social pressures. Since its inception, the work has been widely celebrated for its intellectual rigor and its profound influence on how English grammar is categorized and understood in historical linguistics.
