Give a wide berth means to keep a safe distance from someone or something. In modern English, people use it both literally and figuratively. You might keep away from a physical hazard, or you might avoid a person, place, or situation that could cause trouble.
The phrase comes from sailing. A berth was the space a ship needed when anchored or when moving near other ships, rocks, or shore. Giving a vessel a wide berth meant leaving plenty of room so it could maneuver safely and avoid collision.
That physical idea became a general idiom for staying well clear.
- We gave the flooded road a wide berth after the storm.
- She gives office gossip a wide berth.
The first example is close to the original sense of avoiding danger by keeping distance. The second shows the figurative use, avoiding something likely to bring problems. In both cases, the idea is not just “stay away,” but “stay far enough away to be safe.”
This is why the phrase often suggests caution, not just dislike. If you give something a wide berth, you are deliberately leaving room between yourself and a possible risk.
