Wise means having good judgment that comes from knowledge and experience. A wise person knows facts and understands how to use what they know to make sound decisions and give helpful advice.

Your grandmother might be wise about friendships because she's lived through many relationships and learned what makes them work. A wise teacher knows not just their subject but how to help different students learn in different ways. When you face a difficult choice, like whether to tell a friend something that might hurt their feelings but help them in the long run, wisdom helps you figure out the right thing to do.

Wisdom is different from being smart or clever. You might know a brilliant student who makes foolish choices, or meet someone without much formal education who gives remarkably wise advice. Wisdom combines intelligence with understanding, patience, and insight into how people and the world actually work.

Someone who is wise often thinks before acting, considers consequences, and learns from both successes and mistakes. When a friend makes a wise decision, they've thought carefully about what really matters, not just what seems easiest or most exciting in the moment. The word can also describe a smart choice itself: “It was wise to bring an umbrella” or “That wasn't the wisest plan.”
