Definition of the word subway

The term "subway" originated in the late 19th century, evolving from the concept of underground railways. Initially, "underground railway" was the prevalent term. However, the need for a shorter, catchier name emerged as underground systems became increasingly popular. "Subway" emerged as a popular choice, likely due to its simple and descriptive nature, highlighting the "sub"terranean aspect of these transportation systems. The first recorded use of "subway" was in the late 1880s, referring to the London Underground. It quickly gained traction and became the preferred term for underground railways worldwide.
