Must Know Words for Academic Writing and Tests (IELTS, TOEFL, etc.)

Preparing for academic tests like IELTS, TOEFL, or GRE can feel overwhelming, especially when it comes to mastering the vocabulary.

But don’t worry, building a strong academic vocabulary is not as daunting as it seems. It’s an essential skill that can elevate your writing, boost your test scores, and leave a lasting impression on evaluators.

This guide will walk you through everything you need to know about academic words, their importance, and how to learn them efficiently.

Why Vocabulary Matters

You might wonder, why focus so much on vocabulary? Well, academic writing and standardized tests place significant emphasis on clarity, precision, and variation in language.

Judges want to see how well you can express ideas using rich and precise vocabulary. Whether you’re constructing a persuasive essay or answering a speaking prompt, strong words can help you tackle complex topics effortlessly.

For example, in IELTS, using a range of academic words can increase your band score under “lexical resource.”
