The word "sleeping car" originated in the mid-19th century. Its etymology can be broken down into two parts:
1. "Sleeping": The term "sleeping" comes from the Old English word "slǣpan" which means "to sleep". This word evolved from the Proto-Germanic word "slaepaną". It has remained relatively consistent in its meaning and pronunciation throughout various Germanic languages.
2. "Car": The word "car" originally referred to a wheeled vehicle used for transportation. It derived from the Latin word "carrus" or "carrum", which meant a four-wheeled wagon or cart. The term "car" subsequently evolved in English to refer to a wide range of vehicles, including railway cars.
