sagacious
"Sagacious" is a sophisticated adjective with essentially one core meaning, but it's a word worth knowing because it expresses something more precise than just "smart." It describes a particular kind of wisdom — the kind that comes from sharp judgment and keen insight.
When someone is sagacious, they are not just intelligent — they have the ability to understand situations clearly, make wise decisions, and see things that others might miss. Think of a very experienced mentor or leader who always seems to know the right thing to do. That person is sagacious. It goes beyond book knowledge — it is about practical wisdom and good judgment.

Sagacious can also describe a specific action or decision — not just a person. If a choice or plan shows great foresight and cleverness, you can call it sagacious. Imagine someone who predicts a problem before it happens and prepares for it — their plan would be described as sagacious.
