Expand Your Academic Vocabulary for IELTS
Expanding your vocabulary is a crucial aspect of preparing for the IELTS exam. A rich vocabulary not only improves your comprehension skills but also enhances your ability to express complex ideas. One effective way to expand your vocabulary is by learning about prefixes, suffixes, and root words.
This article explores these linguistic tools, their origins, and provides examples from the Academic Word List (AWL) to illustrate how they can help you build a more versatile vocabulary.
Understanding the Root of a Word
The root of a word is its basic form, carrying the fundamental meaning. By recognising roots, you can often deduce the meanings of unfamiliar words, especially when they are combined with various prefixes and suffixes. For example, the root “act” can lead to related words such as “actor,” “action,” and “activate.”
