Using Word Parts to Improve HESI A2 Vocabulary
Vocabulary questions can become challenging when you encounter a word you have never seen before. One useful strategy is learning how words are built. Prefixes, suffixes, and roots can provide clues about meaning.
What Is a Prefix?
A prefix is a word part added to the beginning of a word. Examples include: pre- = before post- = after anti- = against sub- = under re- = again For example, “preoperative” contains pre-, suggesting something that occurs before an operation.
What Is a Suffix?
A suffix appears at the end of a word. Examples include:
- itis = inflammation
- -ectomy = surgical removal
- -ology = study of
- -less = without
Recognizing these endings can provide useful clues when encountering unfamiliar terminology.
What Is a Root?
A word root carries an important part of a word's meaning. For example, cardi is associated with the heart. Words such as “cardiology” and “cardiac” contain related word elements.
Break Unfamiliar Words Apart
Suppose you encounter an unfamiliar word. Instead of immediately guessing, look for recognizable pieces. Ask:
- Does the beginning contain a familiar prefix?
- Does the ending contain a familiar suffix?
- Does the middle contain a recognizable root?
- What meaning do those pieces suggest together?
This method does not guarantee the correct definition, but it can provide a useful clue.
Build a Vocabulary Notebook
Create three columns:
Prefix/Root/Suffix Meaning Example pre- before prenatal anti- against antibiotic -itis inflammation arthritis cardi- heart cardiac Review a few entries each day rather than trying to memorize a large list at once.
Final Takeaway
Learning word parts can make unfamiliar HESI A2 vocabulary less intimidating. Build your knowledge of common prefixes, suffixes, and roots, then practice using context to determine meaning.
