redden

Have you ever noticed how your cheeks turn red when you're embarrassed? Or how the setting sun makes the clouds look red? To redden means to become red or to make something red. It usually describes a change, not just the color itself. A face may redden from shame, heat, or exercise. The sky may redden at dawn or sunset. A doctor might also say that skin around a cut is reddening, which can be a sign of irritation or inflammation.

To redden means to become red or to make something turn red. It is used when the color changes, whether that happens in a person, in nature, or because of light.

Often, this word is used for faces and skin. Your cheeks may redden when you feel embarrassed, angry, or hot, and skin can redden after exercise, sun exposure, or irritation. If someone says, "Her cheeks reddened with embarrassment," they mean that her face became red because of that feeling.

It is also common in descriptions of nature and light. The sky may redden at sunrise or sunset. Leaves and fruit can redden as they change with the season or become ripe. Firelight may redden a wall or the faces around it.

The word can also suggest emotion in a simple, natural way. A face may redden with anger, shame, or excitement. In most everyday English, it stays close to this visible change in color rather than very abstract meanings.

The key idea is change: something was not red before, and then it starts to look red. That is why "redden" is different from simply saying that something is red.
