Grammar Index - International

The Grammar Index makes English grammar clear - in your own language.

Every grammar topic is defined and explained in the language you choose, while the example sentences stay in English. You understand the rule in your language, then see exactly how it works in the English you're learning.

Whether you're studying for an exam, teaching a class, or simply brushing up on the rules, The Grammar Index gives you a complete, searchable reference plus the study tools to make it stick.
