QUIZ QUESTIONS LISTED AT END OF REVIEW

Vocabulary questions on this part of the TEAS deal with figuring out the meaning of the word based on synonyms, context clues, tone, and your knowledge of roots, prefixes, and suffixes.

UNDERSTANDING SYNONYMS

Synonyms are two words with similar meanings. You may be asked to find a synonym for a certain word or to figure out the meaning of a word in a sentence that provides a synonym for the unknown word.

UNDERSTANDING CONTEXT CLUES

These questions are similar to those in the reading section, but you may be given as little as a single sentence rather than a longer passage. You will need to use that limited context to figure out the meaning of a word. Look at the surrounding context for the word you are given. Figure out the setting in which the word is used. If the word is part of a series, the other words in the series can provide valuable clues. Review the section on homographs in the chapter on spelling. Questions in this section may use homograph to test whether you are paying attention to context. You should also consider the tone of the passage; it may give you a clue about the meaning of an unknown word.




 

UNDERSTANDING WORD ORIGINS

You may also be asked questions about root words, prefixes, and suffixes. A root word is the base form of a word. Affixes are the parts we attach to modify the meaning of the root word. A prefix is attached before the root and a suffix is attached after the root. You should spend some time becoming familiar with common affixes used in the medical profession.
