robust

Imagine an old oak tree standing through storm after storm: that's what this word suggests. It describes someone or something that is strong, healthy, and able to deal well with pressure or damage. A robust system does not fail easily. A robust flavor is rich and strong. You might talk about a robust economy that is growing well, or a robust argument that is supported by solid reasons. Think of it as the opposite of weak, delicate, or easy to break.

The word comes from the Latin robustus, meaning "strong" or "oaken." It is often used for more than physical strength. It also suggests reliability and the ability to keep working well in hard conditions. If a computer program is described as robust, it means it can deal with errors and unexpected input without crashing.

The word "robust" goes beyond simply meaning "strong." It suggests a kind of strength that is built in, not temporary or easily lost. Think of a hearty laugh, full and energetic, or a well-made machine built for heavy use. In both cases, the idea is not just power, but lasting strength.

Originally, it often referred to physical strength or good health, as in a "robust constitution." Today, it is used in many areas. In technology, a robust system can handle errors and unexpected situations without failing. In discussion or writing, a robust argument is one with strong support behind it. In food and drink, a robust flavor is rich, deep, and strong.

You might say a company has a "robust business model," meaning it is built to keep working even in difficult times. You might also describe a person as robust if they seem strong and healthy, or speak of robust growth when something is increasing in a strong and steady way. The word often carries the sense of being able to take pressure and keep going.

So, when you want to express more than simple strength, this is a useful choice. It adds the ideas of health, endurance, dependability, and the ability to hold up well under stress.
