When something redounds to your benefit or credit, it contributes to it or reflects back on you positively. The word describes how actions, qualities, or events circle back to affect someone's reputation or situation.

If you spend months practicing piano and then perform beautifully at a recital, your dedication redounds to your credit: people see the result and think well of you. A team's victory redounds to the glory of everyone who contributed, including the players who sat on the bench. A scientist's discovery might redound to the honor of their university for generations.

You'll encounter redound mostly in formal writing and speeches, where someone wants to emphasize how an action reflects back on a person or group. It almost always appears in phrases like “redound to the benefit of” or “redound to someone's credit.”
