Definition of the word steam

The word "steam" has its roots in Old English. The term "steam" comes from the Old English words "stēam" or "stēamian", which mean "to flow" or "to stream". This is because steam is a type of gas that flows or streams out of a liquid, typically water, when it is heated. In Middle English (circa 1100-1500), the word "steam" took on a more nuanced meaning, referring specifically to the hot vapor that rises from a boiling liquid. This usage is often seen in medieval texts, where "steam" is depicted as a misty or fog-like substance. Over time, the term "steam" has evolved to encompass a range of meanings, including not just the physical properties of steam, but also the concept of steam power and its applications in industry and transportation. Despite its evolution, the word "steam" still retains its roots in Old English, reflecting its deep connection to the natural world.
