The Grammar Index is a complete reference to English grammar, designed for writers, editors, teachers, students, and anyone whose work depends on getting language right. Search clear, authoritative entries covering everything from punctuation and parts of speech to clauses, voice, mood, register, and the structural patterns underlying English sentences. Each entry is concise, example-rich, and free of jargon — written to answer a real question, not to show off terminology.

Hear the word or sentence spoken in a clear, natural voice, and set the reading speed to suit you. The quiz reads each question aloud too. NEW TOPICS Eleven new topics and a new Imagery & Poetry section, covering metaphor, simile, personification, alliteration and more. The quiz knows the difference and asks the right question for each. AND A JOKE Many topics now close with a grammar joke of their own, with its own speaker button. ALSO • Examples keep their emphasis, so the corrected wording in a note stands out. • Cards tell you how many examples a topic has before you open it. • The quiz remembers which topics you have read between visits, so it keeps drawing on what you studied. A shorter version if you prefer bullets: • Read aloud: hear every term, definition, example and quiz question, at your chosen speed • Eleven new topics and a new Imagery & Poetry section • A grammar joke at the end of many topics • Notes keep their emphasis, and cards show the example count • The quiz remembers what you have read between visits ### 1.2.1 — 2026-06-03 What's new in 1.2.1 The word you need to identify in each quiz question is now clearly underlined, so it's easy to see exactly which part of the sentence the question is about. This update also improves startup reliability.
