Billows often form due to the release of energy or displacement of substances, such as strong winds, volcanic eruptions, or fires, and are known for their voluminous and turbulent nature. They typically exhibit a dynamic appearance, resembling the rolling waves of an ocean or the puffy clouds in the sky, which can create a mesmerizing spectacle.
2. Figuratively, billows can also refer to a large and extended mass or surge of any substance or entity, such as water, dust, sound, or crowds. These billows are frequently described in terms of their immense size and rapid movement, reflecting a powerful, expanding force that engulfs or overwhelms its surroundings.
In verb form, "to billow" means:

The word "billows" originated from the Old Norse word "bylgja", which meant "wave" or "swell". It is also related to the Old English word "bylgan", meaning "to swell or rise". Over time, these words evolved into the Middle English word "bilwe", which referred to a large wave or surge of water. Eventually, it transformed into the modern English word "billow" and "billows", which is generally used to describe a large undulating mass of anything, not just water.
