De grondbeginselen der Nederlandsche spelling by L. A. te Winkel is a study of grammar and usage, setting out the rules and forms that govern correct expression. It belongs to the long tradition of works that sought to describe and teach the structure of language in a systematic way.
Preserved here as a free public-domain EPUB, the book is part of Better Gutenberg’s Language & Communication shelf, which gathers foundational texts in linguistics, rhetoric, etymology, and the study of languages. Whether you come to it as a scholar, a student, or a lover of words, it offers a lasting record of how earlier generations understood and described human speech. Note that this volume is written in Dutch.
