Importance of Vocabulary and Grammar in IELTS Speaking. Although there isn’t one particular set of vocabulary and grammar structures you can learn to score high, you should know that your vocabulary should be varied, idiomatic and used appropriately. Spend some time to learn the paraphrasing technique; it’ll prove useful when you need to restate an idea or opinion. Much as the vocabulary, your grammar needs variety as well. Knowing and being able to use a wide range of grammatical patterns, tenses and forms will prove very helpful in your speaking test. You’ll be graded both on your grammar and vocabulary use, each of which is worth 25% of the total score for speaking. While you shouldn’t memorize ready answers (because you’ll be penalized for it!), you can learn words and phrases that frequently come in handy when answering IELTS Speaking questions. These will help you build a better organized and logical speech as well as facilitate examiner’s understanding of your ideas.
