Prefix Four

Four word endings are shown. Pick the single word that can go in front of all four to make real words. Daily and practice.

How to play

  1. Four word endings appear, each starting with a blank, such as ___fold, ___color and ___angle.
  2. Pick the word that can be placed in front of every one of them to make a real word. Here it is TRI.
  3. Only one option works for all four endings. The others break at least two of them.
  4. Wrong picks are greyed out and counted as mistakes. The clock starts on your first tap.

Tips and strategy

  • Test your guess on the ending you find hardest first. If it works there it usually works everywhere.
  • Some beginnings are short, such as UN, RE and TRI, so try small pieces as well as whole words.
  • Read the note after each answer to see the four finished words.
  • A run of questions on the same beginning is rare, so each one is fresh.

FAQ

Is the beginning always a whole word?
No. It can be a prefix such as tri or micro as well as a whole word such as sun or home.
Could another option work on one or two endings?
Yes, but each wrong option is chosen to fail on at least two of the four endings.
Does the daily change?
Yes. A new set of questions is built from the date each day.
