To read German documents, especially those in paragraph and sentence form, it is valuable to have a basic understanding of German grammar. Some recommended resources to learn German grammar are:
- A Foundational Course in Reading German by Howard Martin and Alan Ng.
- Free, online, no previous German experience necessary.
- English Grammar for Students of German by Adam Oberlin, Cecile Zorach and Charlotte Melin.
- A supplemental resource for learning German grammar that explains it from the context of English grammar.
