Prefixes: re-, sub-, inter-, super-, anti-, auto-, mis-
You learn the prefixes re-, sub-, inter-, super-, anti-, auto- and mis-.
How to do the test
- Read the meaning in the sentence.
- Choose the prefix with that meaning, such as re- for again or sub- for under.
- Add it to the front of the word without changing the word.
A worked example
Type the new word. Add a prefix that means "again" to "write": ___
- The prefix re- means again.
- Add it to the front of write and keep the word the same: re + write = rewrite.
- The word is rewrite.
More examples
Type the new word. Add a prefix that means "under" to "marine": ___
- The prefix sub- means under.
- Add it to the front of marine and keep the word the same: sub + marine = submarine.
- The word is submarine.
Type the new word. Add a prefix that means "between" to "act": ___
- The prefix inter- means between.
- Add it to the front of act and keep the word the same: inter + act = interact.
- The word is interact.
Try it yourself
Type the new word.
Add a prefix that means "above" or "more than" to "market": ___
Type the new word.
Add a prefix that means "under" to "marine": ___
Watch out
You change the base word, as in rewrite becoming rewrote.
Only add the prefix. The base word stays exactly the same.
Tips
- Use the meaning of the prefix to guess an unknown word, like subzero.
Why it works
Each prefix carries a meaning: re- means again, sub- under, inter- between, super- above, anti- against, auto- self and mis- wrongly. Knowing the meaning helps you work out new words.
