The prefix con- indicates which meaning?

• A. Against
• B. With
• C. Toward
• D. Before

Answer: (B)

Con- signals togetherness or partnership, giving the sense of “with.” You see this in words like connect, cooperate, and contact, where the idea is bringing things together or acting in concert with others. That makes the meaning “with” the best fit for this prefix. Other prefixes convey different ideas: opposites like against come from contra- or anti-, before from pre-, and toward from ad- or toward. So con- isn’t about opposition or timing; it’s about joining or associating, hence “with.”
