unpolluted

Imagine a mountain spring, bubbling with water so clear you can see the pebbles at the bottom. That is what unpolluted suggests. It means free from pollution or harmful substances, especially in nature. Something unpolluted stays in a clean, natural state. You might describe a remote forest, a river, or the air in the countryside this way when they have not been damaged by smoke, waste, or chemicals.

The word often carries a sense of something valuable that should be protected. It is most often used for air, water, land, and places in the natural world. Think of the phrase "unpolluted air." It brings to mind fresh breezes, open space, and healthy living.

Unpolluted describes something that is free from pollution, contamination, or harmful substances. It is most often used for parts of the environment such as air, water, soil, beaches, forests, or lakes. If a place is unpolluted, it has stayed clean and has not been harmed by things like smoke, trash, sewage, or chemicals. For example, you might say, "The lake was still unpolluted, with clear water and healthy fish," to show that the water remained clean.

The word usually appears in environmental contexts. People talk about unpolluted rivers, unpolluted mountain air, or unpolluted land to emphasize that nature is still in good condition. It often suggests not only cleanliness but also freshness, health, and a natural state that has been preserved.

It can sometimes be used in a wider or more literary way for things beyond the physical environment, but that is less common. In everyday English, the safest and most natural use is for nature and environmental conditions. You may read about efforts to keep a national park unpolluted or to protect an unpolluted coastline, highlighting the importance of preserving natural beauty.

So, whether it refers to air, water, or land, unpolluted points to something clean, natural, and free from harmful human impact.
