The words are chosen editorially; the claims about how GRE Verbal uses them are checked against ETS. The byline is a masthead name, explained in full on who writes this, and the sourcing rules are set out on the standards page.

Once you have worked through all four lists, switch from learning to drilling. Thepractice bank shows the words in real stems, and the daily review built into the 8-week plan keeps them fresh through test day.

How to use this list

Read the cluster blurb first to fix the polarity in mind, then cover the definition column, read the example sentence, and restate the meaning in your own words before checking. One cluster per session, then spaced review the next day and again three days later.

How to actually remember these

  1. Recall, do not reread. Cover the definition, read the example, and produce the meaning yourself. Rereading feels like learning and is mostly forgetting in disguise.
  2. Tie each word to its cluster. Name the cluster and you can usually retrieve the word. The cluster label is the handle your memory grabs.
  3. Write your own sentence. One sentence of your own is worth ten you only read. Make it specific, with a real person and a real moment.
  4. Spaced review. Same day, next day, three days later, one week later. By now you are maintaining all four lists, so rotate one cluster from each per session.
A note on dissipate

Dissipate carries two meanings the GRE likes to play with: to squander resources, and to disperse or vanish. A stem about mist clearing and a stem about a fortune disappearing can both take dissipate. Let the surrounding words, not the word alone, tell you which sense is in play.
