Here are some English words that other words may be derived from. See if you can figure out the form, that is, the correct affix of each derivation. (The first is a freebie.) Look at the word to the left, next look at the meaning the derivation will have, then type in the English derivation with the correct affix (prefix or suffix). When you have written in the derivation, push the button to see if you derived the word correctly.
