The 5-Step Process to Word Mastery

Our system breaks down English vocabulary building into four actionable steps. When you master this, you unlock the ability to understand academic texts and expand your vocabulary for university success.

  1. IDENTIFYING ROOTS: Find the building blocks of words.

  2. ANALYSING AFFIXES: Understand how prefixes and suffixes change meaning.

  3. RECONSTRUCTING MEANING: Put the pieces together to grasp the full meaning.

  4. STRUCTURAL MASTERY: Build a larger vocabulary and stronger language skills.

The Framework

Part 1: The "Front" Builders (Prefixes)

A prefix is a letter or group of letters added to the beginning of a root word to change its meaning. Understanding prefixes is essential for word decoding.

Example:

  • Word: Misunderstanding

  • Prefix: mis- (meaning: wrongly)

  • Root: understand (meaning: to grasp the meaning of)

  • Suffix: -ing (meaning: the act of)

  • The Guess: The act of grasping the meaning of something wrongly.

  • Actual Meaning: A failure to understand correctly.
