The word that has a prefix that means "against" is contradict.

The word that has a prefix that means "against" is "contradict." The prefix "contra-" in "contradict" means "against" or "opposite."

The word that has a prefix meaning "against" is "contra" as in the word "contradict." To determine the prefix of a word, you can break it down into its smaller parts. In the case of "contradict," we have "contra-" as the prefix and "-dict" as the root word. The prefix "contra-" means "against" or "opposite." It is derived from the Latin word "contra," which has the same meaning.

The other words mentioned in your question also have prefixes, but they do not carry the meaning of "against."

For example:
- "Abnormal" has the prefix "ab-," which means "away from" or "off."
- "Excoriate" has the prefix "ex-," which means "out of" or "away from."
- "Distend" does not have a prefix. It is a root word on its own and means "to expand or stretch out."

So, "contradict" is the word that contains the prefix meaning "against."
