Answer:
Anti-intellectual, antislavery, and antonym.
Explanation:
The prefixes that we can add to words to make their mean "against" or "in opposition" to something are anti- and ant-. The word anti-intellectual, use a hyphen (-) to join two parts of a word. In this case, anti functions as a modifier of intellectual. In the other two cases, antislavery and antonym, the prefixes are without a hyphen. But they also mean against. In the case of antonym, the prefix is ant- and the suffix is -onym, which means word or name.
