Sentences & clauses

From simple sentences to relative and participle clauses — the complex structures that unlock Band 7 and above.

Verb patterns & moods

Conditionals, passives, reported speech, modals, and gerund vs infinitive — the verb machinery beyond tense.

Nouns, articles & agreement

Articles, countability, quantifiers, and subject–verb agreement — the accuracy layer where most learner errors live.

Prepositions & linking

In, on, at, dependent prepositions, and the linking words that hold sentences — and IELTS essays — together.

Punctuation

Commas, semicolons, apostrophes, and capitals — small marks with a direct line to your writing band score.

Commonly confused words

Frequently asked questions

Is the SpeakMetry grammar library free?
Yes. Every lesson, every exercise, and the grammar level test are free with no account required. A free account adds progress saving and spaced-repetition review; AI features (the grammar checker and study plans) have free daily limits.
What order should I learn grammar topics in?
Take the free level test first — it estimates your CEFR level and points you at the topics you actually miss. As a rule of thumb: master tenses and articles before clauses, and study complex sentences before Band 7+ structures like participle clauses and inversion.
How is this different from Grammarly or other checkers?
Checkers correct today's text; they don't stop tomorrow's mistakes. Here, every error links to a lesson, every lesson has exercises, and your mistakes feed a spaced-repetition review schedule — plus an IELTS mode that scores grammatical range, which proofreading tools can't see.
How much grammar do I need for IELTS Band 7?
Band 7 requires 'a variety of complex structures' used with 'frequent error-free sentences' — in practice: relative clauses, conditionals, passives, and concession clauses, used accurately. Our IELTS grammar guides break down exactly what each band requires.
