Coaly

Coaly refers to something resembling or containing coal. This term can be used in various contexts, often to describe a color, texture, or substance. For instance, a dark, almost black hue might be described as coaly. In geology, a rock formation with a high proportion of coal would be considered coaly. The term can also be applied to a texture that is dusty, sooty, or gritty, much like the feel of coal dust. Figuratively, "coaly" might describe something that is dark, gritty, or unpleasant, though this usage is less common. Essentially, anything that evokes the characteristics of coal, whether in appearance, composition, or feel, can be described as coaly. The presence of coal or coal-like properties is the defining feature when using this adjective.
