Ember is a small, glowing piece of coal or wood that remains after a fire has burned down. It is often red or orange and can continue to emit heat for a long time, even after the flames have gone out. Embers are commonly found in fireplaces, campfires, and bonfires, where they can be used to rekindle a fire or provide warmth. In addition to its physical form, the term "ember" is also used metaphorically to describe something that is still alive or has the potential to reignite, such as a lingering passion or a fading relationship. This concept can be seen in literature and art, where fire often symbolizes transformation and renewal.
