Which prefix means 'against' or 'opposed'?

• A. For
• B. With
• C. Within
• D. Against each other

Answer: (D)

Opposition in meaning is what this prefix signals. The prefix that means against or opposed is anti-. Since the choices are presented as phrases rather than literal prefixes, the one that best conveys the concept of opposition is the option described as “Against each other.” That phrase captures the idea of two or more things opposing one another, which is exactly what anti- expresses when attached to a root. The other options don’t convey opposition: “For” suggests support, “With” suggests together, and “Within” suggests inside.
