The Internet Grammar of English

The Internet Grammar of English (IGE) is an online course on English grammar, accessible free of charge. Run by University College London (UCL) and designed primarily for university undergraduates, it does not assume any prior knowledge of grammar and is useful to everyone who is interested in the English language, teachers and students alike.

Sections include a glossary and exercises.

UCL's Department of English Language and Literature also has a sister project, The Survey of English Usage.
