Words can be given extra meaning by prefixes at the beginning or suffixes at the end. In this game you have to find the right addition to a word to build up the meaning. When you see the part of a word you want, click on it.

If you are right, you get a point. The word will change to show the new form and you can keep building the word. If you are wrong, the game will tell you, and you will lose a point, but you can try again. There's no time limit, so you can try a different addition to the word, and if you are still wrong you can retry and even keep re-retrying.

There are ten words, so see how many you can build up!
