Master Words in 2 Steps: Recognize, Rebuild, and Retain!

The most interactive way to boost your vocabulary while learning a new language! Our system guides you through 10 words per round using a proven 2-step method:

  • Step 1: Read the definition and pick the correct word from two options.
  • Step 2: Rebuild those exact words by filling in the missing letters from a scrambled list.

Once you ace both steps, the word is marked as "Mastered" and removed from your queue. Stop wasting time on what you already know and focus only on the words that matter!

What you will learn

Advanced vocabulary exercises focus on specialised academic terminology, low-frequency but high-impact words, and precise lexical choices that distinguish expert-level English from intermediate usage. At the C1 level, you will master words used in research papers, policy documents, legal texts, and sophisticated journalism. This vocabulary is essential for achieving IELTS Band 7.5+ and TOEFL 100+.

How to play the Vocabulary Builder

Each session presents 10 C1-level words drawn from academic word lists and professional corpora. The two-step definition and spelling method ensures thorough mastery.

At this level, definitions are precise and academic. Many words have technical or field-specific meanings alongside general usage. The exercise tests the specific meaning relevant to academic English.

💡 Tips for better scores

  • Focus on the precise meaning, not just a general sense. "Mitigate" means to make less severe, not simply to prevent.
  • Learn words in collocational frames: "exert influence," "yield results," "pose a threat."
  • Use newly learned advanced vocabulary in your own writing within 48 hours to solidify retention.

Precision and register in advanced academic vocabulary

At the C1 level, vocabulary learning shifts from "how many words do I know?" to "how precisely can I use the words I know?" The difference between scoring Band 7 and Band 8 on IELTS is not knowing more words — it is knowing the exact word for a specific context. Choosing "exacerbate" instead of "make worse," or "underpin" instead of "support," demonstrates the lexical sophistication that examiners reward.

Our advanced exercises train this precision by presenting definitions that highlight subtle meaning differences. When you learn "ameliorate" (to make a bad situation better) alongside "mitigate" (to make something less severe), you develop the ability to choose the exact word that fits your intended meaning — a hallmark of truly advanced English proficiency.

Example practice items

Here are some examples of the type of content you will encounter at this level:

  • "exacerbate — to make a problem, bad situation, or negative feeling worse"
  • "ubiquitous — present, appearing, or found everywhere"
  • "juxtapose — to place close together for contrasting effect"
  • "proliferation — rapid increase in the number or amount of something"
  • "corroborate — to confirm or give support to a statement or theory"
  • "paradigm — a typical example or pattern of something; a model"
