Mainline is a verb that originally has its roots in the field of rail transport. It is used to refer to the action of placing a transportation vehicle, such as a train or a subway car, onto the main line of a railway network. The main line is the principal route that connects major cities or locations and is used for regular, high-frequency service.
However, the term mainline has also evolved to have a figurative meaning. In a broader sense, it is now commonly used to describe the process of integrating or connecting something into the core or primary aspect of a system, organization, or society. This often implies that the thing being mainlined is recognized as vital, essential, or central to the overall operation or functioning.
For instance, in terms of drug addiction, mainline can describe the injection of a drug directly into a vein, which is the most immediate and direct method of delivery into the bloodstream. In this context, mainline is associated with a high risk due to the intensity and potential dangers involved.
Moreover, mainline can also be used as an adjective when referring to something that is fundamentally established or widely accepted as part of a societal or cultural norm. It indicates that the thing being described is considered to be at the core or mainstream of a particular group or community.
Overall, whether as a verb or an adjective, mainline signifies the connection to a central or principal aspect of a system, activity, or society, either literally or figuratively.
The word "mainline" originated in the early 17th century and has its roots in the combination of two words: "main" and "line".
1. "Main": It comes from the Middle English word "meyne", which meant "chief" or "principal". This further traces back to the Old English word "mægen", meaning "strength" or "power".
2. "Line": It refers to a continuous extent of length. The term has Latin origins, with the word "linea" meaning "a linen thread". Eventually, it evolved to refer to any long, narrow mark or structure.
Putting the two together, "mainline" refers to the principal or chief line. Originally, it was used to describe the principal pipeline in a water system, which later extended to other domains such as transportation and communication.
