sulfrous

Sulfrous refers to something that contains or is characterized by sulfur. It is often used to describe a smell or taste associated with sulfur compounds, such as hydrogen sulfide. For example, "sulfrous" can describe the odor of rotten eggs or the taste of certain mineral waters.

In geology and chemistry, the term "sulfrous" is used to denote the presence of sulfur in various forms. For instance, sulfrous springs are natural water sources that contain dissolved sulfur compounds, often giving them a distinct smell and sometimes medicinal properties attributed to the sulfur. In a broader sense, any substance or phenomenon related to sulfur can be described as sulfrous.

The adjective "sulfrous" is not a formally defined scientific term in the same way that specific sulfur compounds are. Instead, it serves as a descriptive adjective to convey the presence or characteristic nature of sulfur. Its usage is generally understood to relate to the sensory experience of sulfur, primarily its smell and taste, or its general association with sulfurous deposits or emissions.
