English Grammar Rules — Complete Reference
A free, structured grammar reference with clear explanations, right-vs-wrong examples, and a practice quiz on every page.
GramViva is a free English grammar reference built around real classroom teaching. The site covers 218 grammar rules across 30 topics — including verb tenses, articles (a, an, the), conditionals, modal verbs, the passive voice, and reported speech. Each rule is tagged for beginner, intermediate, or advanced learners so you can find content that matches your level.
Every rule page follows the same predictable structure: when to use it, how to form it, side-by-side correct and incorrect examples, common mistakes with explanations, and a short inline quiz so you can check your understanding before moving on. If you are coming from a textbook or a class, you can jump straight to the topic you need — for example, the present perfect or the past simple.
GramViva is free to use, has no ads, and does not require an account. You can browse the 30 categories below or start with one of the beginner-friendly rules further down the page.
