Overview

This chapter is about word meanings. Each question gives a word, either by itself or inside a sentence, and asks which choice means most nearly the same thing. A wide vocabulary helps most, but a few skills can help you handle words you are not sure about.

When the word is in a sentence, read the whole sentence first. The other words often give a clue, such as a contrast word like but or although, or an example that explains the meaning. Try putting each answer choice in place of the word and see which one keeps the sentence's meaning.

Word parts are another strong tool. A root carries the main meaning, a prefix at the front changes it, and a suffix at the end often shows whether the word is a noun, verb, or adjective. For example, the prefix un- means not, and the root port means carry.

Some words also have a positive or negative feeling. If you can tell whether a word sounds good or bad, you can often rule out choices with the opposite feeling. Read all the choices before you pick, because two may look close and only one is the best match.

Key concepts

  • Synonym

    A word that means the same or nearly the same as another word. Most questions in this test ask for a synonym.

    Memory tipSynonym = same meaning.

  • Antonym

    A word with the opposite meaning. Antonyms often appear as wrong choices to trap a quick reader.

    Memory tipMake sure you did not pick the opposite.

  • Context clues

    Hints from the words around an unknown word, such as an example, a definition, or a contrast word like but or however.

    Memory tipSwap each choice into the sentence and reread it.

  • Prefix

    A word part at the start that changes the meaning. Examples: un- and in- (not), pre- (before), re- (again), sub- (under).

    Memory tipPrefix comes first.

  • Root

    The core part of a word that carries its main meaning. Examples: port (carry), dict (say), spect (look), bene (good).

    Memory tipTransport, portable, and import all involve carrying.

  • Suffix

    A word part at the end that often shows the word's role. Examples: -less (without), -ful (full of), -able (can be), -tion (an act or state).

    Memory tipFearless means without fear.

Often tested

  • Read the whole sentence before choosing.
  • Pick the choice closest in meaning, not the opposite.
  • Break long words into prefix, root, and suffix.
  • Use a word's positive or negative feeling to rule out choices.
  • Read every choice before you answer.

Easy to confuse: Word parts

  1. ① cancel
  2. ② delay
  3. ③ attend

  • (C) attend: Attend means to go to the meeting.
  • (D) plan: Plan means to arrange in advance, not to move to a later time.
